Performance analysis of (63, 56) BCH code using Multipath Rayleigh Fading Channel on Spartan-3 FPGA

Performance analysis of (63, 56) binary BCH (Bose-Chaudhuri-Hocquenghem) [1], [4] code has been done through simulations of codec on Matlab (using multipath Rayleigh fading channel realization). Performance was then analyzed on Spartan-3 FPGA and a comparison was carried out. For hardware performance measurement, MHX-2400 2.4 GHz OEM transceiver system has been employed for RF transmission and reception with adjustable power level functionality. MHX-2400 system uses frequency hopped spread spectrum (FHSS) technology and is widely used for telemetry applications. The hardware experiment has been performed in a two story building to virtually simulate multipath phenomena and then the efficiency of codec system is analyzed. This paper explicitly analyses the (63, 56) BCH codec for channel coding applications in satellite and telecommunication systems. The (63, 56) BCH code has codeword length, n = 63 and data block size of, k = 56, rendering a high data rate of 1.125 (n/k) which is quite suitable for applications requiring greater data rate.
