“…Thus, multialphabet CPM schemes are more flexible than multi-h CPM schemes. We note that the multi-alphabet CPM scheme is somewhat similar to the so-called generalized asymmetric multi-h CPM scheme in [13] where the h value depends on both the time and the value of the input symbol.…”

Constant envelope and high spectral efficiency are among the key properties which make continuous phase modulation (CPM) a preferred choice for many applications. Numerous methods are available for designing concatenated CPM systems to achieve additional coding gains. In this paper, we propose a new serial concatenated CPM scheme. Our design uses a multialphabet binary CPM as an inner code, a modified turbo code as an outer code, and specially designed interleavers. The extrinsic information transfer (EXIT) chart technique has been employed to assist the outer code design. Using soft decision decoding, we show that our design gives noticeable improvements compared with previous concatenated CPM schemes over additive white Gaussian noise (AWGN) channel.
