Space-Time Coded Systems using Continuous Phase Modulation

TL;DR: The Rimoldi model of CPM is employed to create a decomposed model of STC-CPM, which allows the search for good space-time codes to take into account the inherent encoding of the modulation.

Abstract: We develop space-time trellis coded (STC) schemes using continuous-phase modulation (CPM). We employ the Rimoldi model of CPM to create a decomposed model of STC-CPM. The decomposition separates the coding from the modulation. The space-time encoding and the inherent CPM encoding is combined into a single trellis encoder on the ring of integers modulo-. This is followed by a bank of memoryless modulators. The model allows the search for good space-time codes to take into account the inherent encoding of the modulation.

- IEEE Transactions on Communications

TL;DR: This work considers high rate space-time trellis codes (STTC) with continuous phase frequency shift keying (CPFSK) and shows that although the schemes do not achieve full transmit diversity, they provide excellent coding gains compared to full rank schemes that have equivalent throughput, but higher order modulations and greater complexity.
