Improving bit error-rate based on adaptive Bose-Chaudhuri Hocquenghem concatenated with convolutional codes

Several algorithms have been proposed to avoid the error floor region, such as concatenation codes that requires high computational demands in addition complexity. This paper proposes a technique based on using cascaded BCH and convolutional leads better correction performance. Moreover, an adaptive method sensing channel's noise determine number of parity bits will be added used reduces consumed bandwidth transmitted is presented. A further enhancement fulfilled by parallel processing branches, resulting reducing time speed up The results show code presents reduction cycles encoding decoding compared with classical finally flexible signal-to-noise ratio channel reduced which reduce bandwidth. MATLAB simulation field programmable gate array (FPGA) implementation provided this validate concept.
