Iterative Decoding of Serially Concatenated Punctured Trellis-Coded Modulation
نویسنده
چکیده
Iterative decoding of serially concatenated code is extended to punctured trellis-coded modulation. A system configuration, a decoding algorithm and a performance evaluation method are proposed. It realizes a total coding rate of m/(m+1) by puncturing parity bits. Simulation results indicate that the proposed system shows no flattening effect which is observed in parallel concatenated system and realizes BER of 10−6 at Eb/N0 = 4.43 dB even with a small interleaver of size 2047. key words: turbo code, trellis-coded modulation, TCM, iterative decoding

Design of serially concatenated systems for long or short block lengths
We study the convergence behavior of iterative decoding of various serially concatenated systems such as a concatenated code, coded transmission over a channel introducing inter-symbol interference, bitinterleaved coded modulation, trellis coded modulation, a.s.o. We use EXIT charts to construct simple irregular codes, which can significantly improve the convergence behavior of iterative decodi...
متن کاملPerformance of trellis-coded CPM with iterative demodulation and decoding
Interleaved trellis-coded systems with full response continuous-phase modulation (CPM) are considered. Upper bounds on the bit-error rate performance are derived for coherent detection on the additive white Gaussian noise and flat Rayleigh fading channels by considering the trellis code, interleaver, and CPM modulator as a serially concatenated convolutional code. A coherent receiver that perfo...
متن کاملIterative Demodulation and Decoding of Trellis Coded CPM
Interleaved trellis coded systems with continuous phase modulation (TCCPM) are considered. It is shown that the combination of a trellis code, interleaver and the CPM modulator results in a significantly enhanced distance spectrum for the transmitted signals. Upper bounds on the bit error rate are derived by considering the combination of the trellis code, interleaver and the CPM modulator as s...
متن کاملNoncoherent iterative decoding of spectrally efficient coded modulations
In this paper, we consider possible solutions for noncoherent decoding of concatenated codes with spectrally efficient modulations. Two main classes of schemes are considered. A first class is obtained by concatenating parallel coding schemes with differential encoding. A second class considers serially concatenated coding structures and possible schemes derived from turbo trellis coded modulat...
متن کاملPerformance of Coded Offset Quadrature Phase-Shift Keying (OQPSK) and MIL-STD Shaped OQPSK (SOQPSK) with Iterative Decoding
We show that, similar to the trellis-coded modulation representation of MIL-STD shaped offset quadrature phase-shift keying (SOQPSK), offset quadrature phaseshift keying (OQPSK) can be decomposed into a “degraded” trellis encoder and a memoryless mapper. Based on the representations of OQPSK and MIL-STD SOQPSK as trellis-coded modulations, we investigate the potential coding gains achievable fr...
