This chapter gives an overview of the literature survey on LDPC block codes and algorithm for LDPC decoder which gives a high throughput, better bit error rate performance with low clock frequency. R G Gallager [1] in his paper, the overview of low density parity check codes are presented. The parity check matrix specifies these codes, which consists of few entries of non-zero elements. The number of non-zero elements in row should be greater than the number of non-zero elements in column. The typical

EE – 653 CODING THEORY PROJECT REPORT REDUCING THE GAP TO CAPACITY OF A RATE 1/3 CODE VIA CONVOLUTIONAL ENCODING/DECODING ARUN PRAKASH NACHIMUTHU MARIA HASHMI ABSTRACT In this project we are trying to minimize the gap-to capacity of a channel given by Shannon’s theoretical limit of a rate 1/3 code. This is done through a convolutional encoding/decoding by varying memory elements for both soft and hard decision decoding. The basic concepts associated with the convolution code with its encoding

Performance of Space Time Block Codes(STBC) Anuj Mehta School of Electrical Engineering & Telecommunication, UNSW Sydney, Australia Z3488506@zmail.unsw.edu.au Abstract— In the following paper we are going to discuss the different coding techniques such as Orthogonal STBC , Alamouti’s coding and their performance on a QPSK signal with Rayleigh fading. We will plot it for SNR values ranging from 0dB to 40 dB. In this we will be taking different combination for number of transmitting and the radiating

Improvements of Block Based Pass Parallel in Image Compression Algorithm Dhivya.T1 1Student, Dept. of ECE, Vivekananda College of Engineering for Women,dhivyatkalai@gmail.com Nirmala.R2 2Assistant professor, Dept of ECE, Vivekananda College of Engineering for Women,nirdha06@gmail.com Abstract¬--- A algorithm for wavelet transformed images. BPS is block based pass parallel SPIHT is one of the widely used compression much simpler and faster than many existing compression techniques

Literature Survey: Cooperative diversity for a simple three-terminal relay channel was first introduced in [12]. Later, in [1], several improvements were made in capacity bounds and cooperative schemes, such as decode-and-forward, were introduced. Modifications to amplify-and-forward scheme were proposed in [13-16]. Based on these, more relaying schemes were introduced in [17-24]. The performance and other characteristics of the aforementioned schemes in several environments were studied in [17-27]

Abstract—Abundant use of electronic communication has paved way for transmitting information securely. Security has its importance and application in wide area. It is a measure of human negligence, in desire to enclose the latest technological inventions. This measure may have drastic effect on human conception to the positioning of application, which needs a determined concern in terms of security. Audio steganography is the science of hiding some secret text or audio files in a host audio file

The paper display the adjusted fix radio wire for 3GHz recurrence, in the paper distinctive methodologies is delivered by fluctuating opening and DGS into the reception apparatus, proposed recieving wire gives double band operation and shows great recreated comes about for two recurrence groups. Return loss of conclusive outline was - 11.75 dB for 3 GHz recurrence and VSWR of 1.68 and - 17.86dB and VSWR of 1.28 for 5GHz frequency.[7] In the paper DGS is utilized to builds the pick up and diminishes

Have you experienced Information overload? What are your solutions/suggestions for reducing the overload? Most recently while taking a program management course at work, I experienced information overload. This was an online course that had a ton of information that I was required to decipher and pass all tests with 100% within sixty days. The material was very informative, however, it was somewhat stressful for me to retain all the information within the allotted time, especially since this was

4.2 Implementation Details 4.2.1 Data Source Random Bernoulli generator generates binary data on a per frame basis. In data output, 144 samples per frame are used, and data rate is 36 Mbps. Figure 4.2: Data Source 4.2.2 Forward Error Correction Coding A typical problem in OFDM based systems is a high Peak-to-Average Power Ratio (PAPR). The available RF power amplifiers usually have a limited linear dynamic range. This is not a problem for constant amplitude signals, however, in OFDM, due to IFFT
