Abstract

It is well known that the rate (n - 1)/n convolutional codes combined with 2n-level CPM have good power-bandwidth performance with encoder independent upper bounds. In the Letter, a scheme combining rate 2/3 convolutional codes with 8-level multi h CPM is shown to have better power-bandwidth performance over the upper bound than the scheme with single h. Results obtained over a wide range of h combinations are also presented.
