This paper details the application of a PEG originated non-binary LDPC codes designed to fit the pay load size of MAC frame of IEEE 802.15.6 Wireless Body Area Network. The resulted codes are with the block size is 255 bytes. Codes with the rate of 0.5 and 0.9 are investigated for their performance. The symbol error rate and block error rate performance given by the system simulation has confirmed that the non-binary LDPC code can yield better performance when compared with hard decision Reed Solomon codes.
