One of the dramatic developments in bandwidth-efficient communications over the past few years is the introduction and rapid applications of combined coding and bandwidth efficient modulation, known as coded modulation, for error control. Using coded modulation, reliable data transmission can be attained without compromising bandwidth efficiency. Presented here are the basic concepts of coded modulation. Two simple examples are used to demonstrate how significant coding gains can be achieved without bandwidth expansion. Lin, Shu Unspecified Center NAG5-931

The New Mexico State University Center for Space Telemetering and Telecommunications systems has been, and is currently, engaged in the investigation of trellis-coded modulation (TCM) communication systems. In particular, TCM utilizing M-ary phase shift keying is being studied. The study of carrier synchronization in a TCM environment, or in MPSK systems in general, has been one of the two main thrusts of this grant. This study has involved both theoretical modelling and software simulation of the carrier synchronization problem.

The basic concatenated coding system for the space telemetry channel consists of a Reed-Solomon (RS) outer code, a symbol interleaver/deinterleaver, and a bandwidth efficient trellis inner code. A block diagram of this configuration is shown. The system may operate with or without the outer code and interleaver. In this recommendation, the outer code remains the (255,223) RS code over GF(2 exp 8) with an error correcting capability of t = 16 eight bit symbols. This code's excellent performance and the existence of fast, cost effective, decoders justify its continued use. The purpose of the interleaver/deinterleaver is to distribute burst errors out of the inner decoder over multiple codewords of the outer code. This utilizes the error correcting capability of the outer code more efficiently and reduces the probability of an RS decoder failure. Since the space telemetry channel is not considered bursty, the required interleaving depth is primarily a function of the inner decoding method. A diagram of an interleaver with depth 4 that is compatible with the (255,223) RS code is shown. Specific interleaver requirements are discussed after the inner code recommendations.

In this thesis, the last-mile and home-LAN interference problems of VDSL systems are addressed using turbo codes. With regard to the last-mile problem, a bandwidth efficient turbo coding scheme is proposed in which, turbo codes are combined with bandwidth efficient modulation and the soft information is exchanged between the decoder and demodulator in an iterative manner. The scheme is investigated for various values of transmitting power, signal frequencies and numbers of crosstalkers for a targeted BER of 10 -5 . The effects of various code parameters on the performance of VDSL modems are explored. In order to reduce the latency at the receiver end, a pipelined decoding scheme is proposed. Simulation results are presented and compared with that of the 4D Wei-RS scheme. The results show that the choice of turbo codes not only provides a significant coding gain over the standard FEC scheme but also efficiently maximizes the loop length and bit rate at a very low transmitting power in the presence of dominant far-end crosstalk (FEXT). In order to compare the hardware complexity, the proposed and 4D Wei-RS schemes are synthesized using SYNOPSYS with the target technology of Xillinx 4010-3. The Xilinx FPGA statistics of the proposed scheme is compared with that of the 4DWei-RS scheme. To mitigate the effect of home-LAN interference, an iterative soft interference cancellation and decoding technique is proposed in which, the VDSL and home-LAN signals are jointly detected using a soft interference canceller and a soft-in soft-out demodulator combined with a set of turbo decoders.
