Overview of Performance of Coding Techniques in Mobile WiMAX Based System

Abstract

In this paper, we present the review of the convolution coding (CC) and convolutional product code (CPC) based on mobile WiMAX system. In coding techniques the number of symbols in the source encoded message is increased in acontrolled manner in order to facilitate two basic objectives at the receiver one is Error detection and other is Error correction. The amount of error detection and correction required and its effectiveness depends on the signal to noise ratio(SNR). The WiMAX technology based on standard 802-16 wireless MAN is configured in the same way as a traditional cellular network with base stations using point to multipoint architecture to drive a service over a radius up to several kilometers. The range and the Non Line of Sight (NLOS) ability of WiMAX make the system very attractive for users, but there will be slightly higher BER at low SNR. Coding is a technique where redundancy is added to original bit sequence to increase the reliability of the communication. This paper reviews the code used in mobile WIMAX. A detailed description of the coding techniques in WIMAX system is studied.
