Serial concatenated trellis coded modulation with inner rate-1 accumulate code
GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270)
Preserved Fulltext
In this paper we propose a Serial Concatenated Trellis Coded Modulation system using one or more inner accumulate code(s) and a Gray-labeled signal constellation. ...
Despite the simple inner code, the simulated performance in AWGN and Rayleigh fading is comparable to that of more complex systems suggested in the literature. ...
Though the proposed system uses a simple inner accumulate code, in AWGN it performs comparably to serial concatenation schemes recently reported in the literature [6] that use more complex rate-1 inner ...

We show that a high rate serially concatenated code used in conjunction with a precoded partial response equalized magnetic recording channel and iterative decoding can provide similar performance to a ...
The precoded partial response maximum-likelihood (PRML) read channel is incorporated as the inner code of the concatenated coding scheme and the outer code is a high rate convolutional code. ...
Consider having just a precoder of the form 1/(1@ D) as the inner code for a serial concatenation system in comparison to having a precoded 1,-D channel as the inner code. ...

This paper proposes a class of full space diversity full rate space-time turbo codes. Both parallel concatenated and serially concatenated codes are designed. ...
We also study the robustness of performance of both turbo codes and trellis codes in space-time correlated fading channels. ...
More recently, it is proposed in [16] that a space-time trellis code is serially concatenated with interleavers and a rate 1 recursive inner code ( Figure 6 ). QPSK modulation is considered there. ...

In this paper we address these design issues by suggesting a new class of TLCs that we call Systematic with Serially Concatenated Parity (S-SCP) codes. ...
We describe two other members ofthisfamily that both exhibit good performance over a wide range of block sizes, code rates, modulation, and target error probability. ...
The new TLC is a systematic code with parity bits generated using a serial concatenation of an outer code, an interleaver and an inner recursive parity generator as illustrated in Fig. l(a) . ...

concatenated turbo schemes with low density parity check (LDPC) codes and continuous phase modulation (CPM) based on Laurent decomposition. ...
By inserting partial interleavers between LDPC and CPM and allowing degree-1 variable nodes under a certain constraint we show that designed rates are very close to the maximum achievable rates. ...
If several papers consider the serial concatenation of CPM with trellis based codes [2] [3] [4] [5] , only few references studied the concatenation with Low-Density Parity-Check (LDPC) codes. ...

Extrinsic information transfer (EXIT) charts are used to design systematic and nonsystematic repeat-accumulate (RA) codes for iterative detection and decoding. ...
The convergence problems of nonsystematic RA codes are solved by introducing a biregular, or doped, layer of check nodes. ...
Systematic RA codes are not serially concatenated codes because both the inner and outer decoders receive channel information. ...
