“…Alternatively, it is possible to separate a trellis encoder from the CPM modulator by a symbol-interleaver, which allows the demodulation process to be decoupled from the decoding process [6], [7]. Such systems are known as trellis coded CPM (TCCPM) [8].…”

This paper investigates a capacity-based approach to parameter optimization for energy and bandwidth efficient communication systems. In particular, noncoherently detected, bit-interleaved coded, M -ary Gaussian frequency shift keying (GFSK) is considered. Noncoherent detection is accomplished using a sequential, soft-output (SO), soft-decision differential phase detector (SDDPD). The capacity of the proposed system under modulation, channel and detector design constraints is calculated. For a wide range of spectral efficiencies, the most energy efficient combination of GFSK parameters and code rates is identified using information theoretic bounds on reliable signaling. The information outage probabilities under modulation and detector design constraints are calculated for the block fading channel. Select results reveal that the capacity-based approach also helps in identifying the combination of modulation parameters and code rates with the lowest outage probabilities in block fading.

Abstract-The design of bit-interleaved coded continuous phase modulation (CPM) is characterized by the code rate, alphabet size, modulation index, and pulse shape. This paper outlines a methodology for determining the optimal values of these parameters under bandwidth and receiver complexity constraints. The cost function that is used to drive the optimization is the informationtheoretic minimum E b /N 0 , which is found by evaluating the constrained channel capacity. The capacity can be estimated using Monte Carlo integration. A search for optimal parameters is conducted over a range of coded CPM parameters, bandwidth efficiencies, and channels. To limit complexity and allow any modulation index to be considered, the receiver is constrained to use a soft-output differential phase detector. Bit error rate curves using a binary turbo code confirm that the constrained capacity is a very good indicator of the performance of the complete system. Index Terms-Bit-interleaved coded modulation (BICM), capacity, continuous phase modulation (CPM), differential phase detector.

“…The outer codes used in [13]- [16] are binary. However, the decoding in [13,14] is non-iterative. Also, the reason for using symbol-wise interleavers in [15,16] is not clear and the advantages of the symbol-wise approach are not demonstrated.…”

Serially concatenated continuous phase modulation (SC-CPM) is known to be a preferred choice of modulation technique for achieving high efficiencies in bandwidth and power. Commonly used SCCPM schemes use bitwise interleaving for concatenations. In this paper, we consider symbolwise interleaving based on a decoding error analysis. We show that, by using an appropriate decoding algorithm, this symbol-wise scheme of SCCPM leads to considerable improvements in bit error rate (BER) performance over the scheme using bitwise interleaving.
