interference (ISI). ISI is caused by dispersive channel. As higher data rate requirement for this OFDM is very important and for the subcarrier modulation using the different type of modulation technique such as Quadrature Amplitude Modulation (QAM) or Phase Shift Modulation (PSK) [3]. The Inverse Fast Fourier Transform (IFFT) and the Fast Fourier Transform (FFT) are very effectively use in OFDM transmitter and receiver. These algorithms are very important for the OFDM to prove higher scalability above the

composite fading channel i.e. generalized K- fading channel. Here, OFDM system is considered which include repetition code to enhance the wireless link performance with simplicity. Symbol error rate (SER) performance is evaluated using binary phase shift keying (BPSK) and 16-qardature amplitude modulation (16-QAM) over generalized-K fading channel. This channel model considers Nakagami-m distribution to define multipath and gamma distribution to represent shadowing. Simulation results demonstrate that

Coherent Optical-Orthogonal Frequency Division Multiplexing (CO-OFDM) technique is extensively reconnoitered for next generation optical communication system emerges attractive pathway towards

The following is expected from a microwave radio link when it is deployed (7) in a 4G network:  Carry multiservice traffic over microwave links cost-effectively  Increase the transport bandwidth capacity for data services  Maximize the spectral efficiency  Provide carrier grade manageability and survivability of multi-service transport In order to meet afore mentioned expectations, with an eye on 3Cs, is the biggest hurdle. The migration to all IP network is going to be a tedious transition (8)

Cooperative communication is a new concept of research and it is a powerful technique to mitigate fading in wireless relaying layout. Concerning with the fading problem, this paper is focuses to give a better non-orthogonal space-time block code (STBC) scheme and assimilate it in the cooperative relaying nodes for upgrading performance of the system. Golden coded has also been incorporated in IEEE 802.16 (Wi-MAX) standard as a full rate full diversity space-time code and proven to present a ranking

I. INTRODUCTION Technology is an essential part of human development, but with technological advancements we can see our lives being changed every single day. In Sao Paulo, technology is on the rise and is slowly catching up with the United States and other countries that are quickly developing. With a generation of kids in the United States that have connection to anything at their fingertips, we can notice that our perspectives and modalities are always adapting. America has developed wireless

which include Amplitude shift keying, Phase Shift keying, Frequency Shift keying and Quadrature Phase shift keying have been demonstrated by creating a model using the blocks and channels available in the Simulink library. The signal used in all of the experiments which is to be transmitted is a randomly generated sequence of bits and the carrier signal used is a high frequency sinusoidal signal. All of these experiments vary a characteristic (frequency, amplitude and phase) of the carrier sinusoid
