N2 - In this paper, we make a performance comparison between convolutional(171,133) codes (CC), concatenated RS(255,239)-convolutional(171, 133) codes (RS-CC) and LDPC(672,336) based on 60GHz single carrier physical layer (SC-PHY). With the effect of phase noise and non-linear distortion of power amplifier (NLPA) taken into account, RS-CC reveals higher robustness against the effect over LDPC, and it has the better bit-error rate performance than LDPC. Over and above, a forward independent sliding-block architecture for Viterbi decoders (FISB-VD) is proposed to achieve multigigabit inner-CC decoding of the RS-CC. A 16-parallel FISB-VD has been implemented in a Xilinx Virtex-6 FPGA device, of which the maximum decoding rate can be up to 3.2 Gbps.
