Abstract In this paper a method of joint source/channel coding is presented. For a source with separate symbols, codes having desired minimum Hamming distance dmin are selected within range [0,1). Then, under the case having channel error, the decoder utilizes the dmin, the corresponding relationship between code and symbol, and the statistical characteristic of source to recover the original sequence of symbols without the use of channel coding. The introduced scheme is suitable for bandwidth-limited binary symmetric channel (BSC) with fairly high error rates.
