Analysis of Cooperative Networks Based on WiMAX LDPC Code

摘要: This study focus on the performance analysis of Cooperative communication networks based WiMAX Low Density Parity Check (LDPC) codes. The channel capacity approaching coding technique LDPC having gain method Bit Interleave Coded Modulation with Iterative Decoding (BICM-ID) is used. different fading environment analyze to counter challenges in wireless and provides solutions for drawbacks multiple input output MIMO technology. relays are used communications increases range link reliability at a lower transmit power because once signal loses its strength it's amplify relay node when it suffers from noise also decoded which reliability. iterative decoding BER only small amount decibel attain Shannon limit. open way technology can be by using above mention system will rate, cost, less complexity power.
