Highly Bandwidth-Efficient Concatenated Multidimensional Trellis Coded Modulation
نویسندگان
چکیده
The demand for high data rates in coded OFDM systems requires codes with high bandwidth efficiencies. A recently introduced concatenated coding scheme employing trellis coded modulation (TCM), the so-called staggered TCM, is very promising for this purpose. Due to its block-convolutional structure an iterative decoding procedure is possible whereas the rate of the constituent TCM is preserved for the overall code. In this work, multidimensional TCM is used as constituent code to increase the bandwidth efficiency of the original construction.

A Reduced-Complexity, Highly Power-/Bandwidth-Efficient Coded Feher-Patented Quadrature-Phase-Shift-Keying System with Iterative Decoding
Based on a representation of Feher-patented quadrature-phase-shift keying (FQPSK) as a trellis-coded modulation, this article investigates the potential improvement in power efficiency obtained from the application of simple (a small number of states) outer codes to form a concatenated coding arrangement with iterative decoding. Several possible configurations for the concatenation are suggeste...
متن کاملA concatenated coded modulation scheme for error control
This paper presents a concatenated coded modulation scheme for error control in data communications. The scheme is achieved by concatenating a Reed-Solomon outer code and a bandwidth efficient block inner code for M-ary PSK modulation. Error performance of the scheme is analyzed for an AWGN channel. We show that extremely high reliability can be attained by using a simple M-ary PSK modulation i...

Trellis coded modulation (TCM) is a bandwidth efficient transmission scheme that can achieve high coding gain by integrating coding and modulation. This paper presents an analytical expression for the error event probability of concatenated space–time block coding with TCM which reveals some dominant factors affecting the system performance over slow fading channels when perfect interleavers ar...

This paper presents a family of concatenated twostate trellis-coded modulation (CT-TCM) schemes. Compared with the existing turbo-type bandwidth-efficient coded modulation schemes, the proposed codes have significantly reduced complexity without sacrificing performance. A joint design strategy for all component codes is established. This leads to so-called asymmetrical and time-varying trellis ...
متن کاملPerformance of Hybrid Concatenated Trellis Codes CPFSK with Iterative Decoding over Fading Channels
Concatenation is a method of building long codes out of shorter ones, it attempts to meet the problem of decoding complexity by breaking the required computation into manageable segments. Concatenated Continuous Phase Frequency Shift Keying (CPFSK) facilitates powerful error correction. CPFSK also has the advantage of being bandwidth efficient and compatible with non-linear amplifiers. Bandwidt...
