Noncoherent coded continuous phase modulation
Continuous phase modulation (CPM) systems for noncoherent coded transmission are proposed and analyzed. Specifically, the application of a feedback–free modulator is regarded. For demodulation, a receiver structure which requires only two or three linear filters is considered. For decoding, noncoherent sequence estimation (NSE) with Viterbi decoding and per–survivor processing is applied. Notew...
متن کاملConvergence Analysis for Turbo Tellis Coded Modulation
In this paper we extend the previously proposed extrinsic information exchange charts (EXIT) method for the analysis of the convergence of turbo codes to of turbo coded modulation (TTCM) schemes. The effectiveness of the proposed method is demonstrated through examples. The proposed method provides a convenient way to systematically compare between schemes and thus can be used as a tool in the ...

ABSTRACT In this paper, we investigate the performance of Turbo Trellis Coded Modulation (TTCM) over AWGN, and Rician channels and assume that phase disturbance is available. As we know Turbo Trellis Coded Modulation (TTCM) is similer to binary turbo codes, but employs Trellis Coded Modulation (TCM) codes which include multi-dimensional codes. The combination of turbo codes with trellis codes l...
متن کاملDifferential Turbo Coded Modulation over Unsynchronized Channels
A simple serially concatenated turbo code using differential 8PSK modulation as the inner code and a [3,2,2] parity code as the outer code is studied. This inner code allows for noncoherent operation, but is decoded coherently according to turbo principles with iterative exchange of extrinsic probabilities. Results show a turbo cliff at 4.4 dB, about 1.5 dB away from the 8PSK channel capacity. ...
متن کاملParallel concatenated turbo codes for continuous phase modulation
There are several ways to use iterative decoding techniques with coded continuous phase modulation (CPM). This paper presents a method using parallel concatenation of convolutionally-coded CPM. All CPM schemes can be decomposed into a ring convolutional code and a memoryless signal mapper. This allows a properly designed convolutional code trellis to be combined with the CPM trellis, producing ...
