The stream of complex numbers is rearranged so that the pilots can be inserted. In each OFDM symbol, four pilot signals are inserted in order to make the coherent detection robust against frequency offsets and phase noise. The pilots are BPSK modulated by a pseudo binary sequence to prevent the generation of spectral lines [18]. A zero padded block adds zeros, in the right places, to adjust the IFFT bin size to length N. Selector block rearranges the sub-carriers so that real signal output can be generated. The IFFT block then computes the Inverse Fast Fourier Transform (IFFT) of length N, where, for ease of implementation, N is a power of

The complexity and memory requirements of the algorithm are in the order of $D_\mathcal{D}.{\rm N}$, denoted as $O(D_\mathcal{D}{\rm N})$. The algorithm become more effective when the minimum difference $\Delta Y_k$ is large between the transmission probability gains $Y_k$. Consequently, our algorithm finds an optimal solution coupled with linear complexity, when the network become more heterogeneous due to small ${\rm N}$. Our algorithm also finds the optimal solution with an increased complexity, when the network becomes more homogeneous or less heterogeneous due to increasing ${\rm N}$. The quantization precision ${\rm N}$ in Algorithm 1, is a physical quantity specified by the underlying network that elaborate the designing of quantization step. The total content size $H$ depends on the required content transmission rate $r_{c_i, d_i}$ and $Y_k$, whereas $Y_k \sigma$ are defined by the contact dynamics of the nodes in a network. However, if the network is difficult by the required level of transmission ratio, the values of $Y_k$ and the value of $\Delta Y_k$, such that $\rm N$ is too large, then the designer may have to comprise by reducing the desired level of transmission ratio to reduce $\rm N$. In results, the sub-optimal

Spectrum sharing: Since there may be multiple CR users trying to access the spectrum, their transmissions should be coordinated to prevent collisions in overlapping

Step:1 Choose two large primes from random x,y Step:2 find the system modules N= x.y: *(N)=(x- 1)(y-1) Step3: encryption key e lies in 1<e<*(N),gxy(e,*(N)=1 Step4: Decryption key d is calculated then e.d=1, mod*(N) and 0 ≤ d ≤ N.

Since CC combat the signal fading, it can be used to extend the transmission range of nodes and the network connectivity \cite{Yu2010,Zhu2012}. Figure \ref{fig:AumentoRaio} exemplify how CC can be used by node $v_i$ to send data to node $v_j$ that is outside of its maximum transmission range $R_{MAX}$. The source node $v_i$ selected the node in green as its helper. The dotted line represents the direct communication of the first phase, between the source and the helper. The solid arrows represents the second phase, where the source and its helper send data cooperatively to the destination. The nodes in black, that are inside $R_{MAX}$ could be selected to be included in the helper

We were assigned to construct a software that utilizes a classification algorithm that is able to accurately decide a correct classification for a certain sequence of inputs that were provided by the user. The input is to be classified based on a known training set of records of the same attributes as the sequence provided by the user.

Exploiting the tensor product structure of hexahedral elements expresses the volume operations as 1D operators. The details are presented in algorithm \ref{alg_hexvol}.

Given a set of equation axioms and a set of related reduction orderings, the standard completion procedure KB [5] orients the equations into rewrite rules and tries generating complete TRS equivalent to the input equation axioms. The appropriate given reduction orderings lead the procedure to success while the others to diverge or fail which makes it hard to test all candidate orderings in sequence or physically paralleled environment.

13 to 30 percent of the perceived similarities in our exams can be attributed to the nature of computer science and is expressed in the data outlined by Professor Barker. When answering problems associated with this exam it is not hard to conceive the fact that a majority of individuals in the class will come to discover the right answer to a question in the exact same manner. Introductory to computer science is meant to be simplistic in approach, and because of this fact many problems on the exam were both extremely similar to examples given in class, on labs, and projects, and on drill quizzes that were done throughout the semester.

The paper I read is “Noncooperative Cellular Wireless with Unlimited Numbers of Base Station Antennas” written by Thomas L. Marzetta. This paper was published in IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS, VOL. 9, NO.11, NOVEMBER 2010. The pilot signal is a direct sequence spread spectrum signal continuously sending by the base station. It makes the base station could send data in the forward-link and demodulate cell phone signals in the reverse-link. The pilot signal is known as confessed, like 000000 or 111111. In frequency re-use technology, we divide the space into several cells. Due to the same or correlated pilot sequence re-use in contiguous cells, the base station will inadvertently send data to terminals in other cells or collect and combine reverse-link signals from terminals in other cells when processing. This is called pilot contamination. In this paper, the author mainly talk about the environment of multi-user(MIMO) operation with an infinite number antennas in the base station. He thinks that in this

The turbo principle has been extended into new receiver topologies such as turbo detection, turbo equalization, turbo-coded modulation, turbo MIMO, etc. In the case of transmission systems with interference, such an iterative receiver, known as turbo equalizer or turbo detector achieves significant gains in BER performance, compared with a non-iterative scheme. However, the design of high throughput, low complexity and low latency architectures for a receiver that contains an iterative process is a great challenge.
