Serially Concatenated Continuous Phase Modulation with Ring Convolutional Codes

摘要

Serially concatenated continuous phase modulation (SCCPM) systems with ring convolutional codes (CC) are investigated. Both EXIT chart and union bound techniques are used to compare with the simulation results and are used as analysis tools. The latter is for the first time generalized to a non-binary interleaver for a serially concatenated system, where both the order and position of the permuted non-zero symbols have to be considered.
