Abstract:
This paper investigates the performance of turbo coded continuous
phase modulation (CPM). The proposed system uses standard binary turbo
codes on M-ary input CPM channels by applying bit-interleaved
coded-modulation (BICM), and thereby converting CPM channels into
binary-input channels. Simulation results presented in this paper
show that the turbo coded CPM signaling outperforms various other
coding techniques for CPM signaling which are based on convolutional
codes. The performance of the CPM signaling is compared to that
of the phase-shift-keying (PSK) signaling and it is shown that the
CPM signaling provides a more favorable trade-off between bandwidth
and energy.
