The proposed architecture has the cell size of 455K, and uses 221,184bits of shared memories. The throughput of rate- 1/2 decoder is 14.32 Mbps, and that of rate-3/4 decoder is 26.97Mbps at clock frequency of 185MHz. All these throughputs meet the performance requirement of the CMMB standard. The throughput requirement for rate-1/2 decoder is 10.852Mbps, and that for rate-3/4 decoder is 16.243Mbps. As mentioned earlier, this paper is the first paper to design an LDPC decoder for CMMB. So we could not find any reference to compare our design with. Designs in [5] and [10] are LDPC decoders targeted for DVB-S2. So it is not reasonable to compare the designs with the proposed one because they are based on a totally different H-matrix.
