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