Abstract This thesis introduces an LDPC decoder that is capable of providing high bandwidth needed for next generation standards and flexible to support future standards. It implements the message passing decoding algorithms with a combination of unicast and multicast communications between processing elements. The goal is to reduce the communication overhead and keep the processing elements as simple as possible. The suggested decoder works in one of two modes by implementing two decoding algorithms. The first mode implements the sum-product decoding algorithm that offers the best bit error rate (BER) performance making it suitable for modern communication applications requiring the most accurate error correction performance with moderate data rates. The second mode implements the min-sum decoding algorithm which is much simpler and achieves even higher bitrates with acceptable BER performance degradation making it suitable for higher data rates applications with better SNR situations such as stationary WIFI hotspots and wired communications. |
