N2 - We show that a recursive cost-constrained random coding scheme attains an error exponent that is at least as high as both the random-coding exponent and the expurgated exponent. The random coding scheme enforces that every pair of codewords in the codebook meets a minimum distance condition, and is reminiscent of the Gilbert-Varshamov construction, but with the notable feature of permitting continuous-alphabet channels. The distance function is initially arbitrary, and it is shown that the Chernoff/Bhattacharrya distance suffices to attain the random coding and expurgated exponents.
