Bandwidth-efficient correlative trellis-coded modulation schemes
A novel digital modulation scheme is proposed that allows to increase the data rate compared to uncoded modulation when the out-of-band power is fixed. If the data rate remains unchanged, this corresponds to a bandwidth reduction that is achieved by shaping the signal spectrum by the introduction of correlation in the transmitter. This correlation has to be resolved in the receiver by a maximum...
متن کاملHighly Bandwidth-Efficient Concatenated Multidimensional Trellis Coded Modulation
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 f...
متن کاملBandwidth-Efficient Turbo Trellis-Coded Modulation Using Punctured Component Codes
We present a bandwidth-efficient channel coding scheme that has an overall structure similar to binary turbo codes, but employs trellis-coded modulation (TCM) codes (including multidimensional codes) as component codes. The combination of turbo codes with powerful bandwidth-efficient component codes leads to a straightforward encoder structure, and allows iterative decoding in analogy to the bi...
متن کاملBandwidth-efficient constant-energy trellis-coded modulation schemes with prescribed decoding delay
For a general class of constant-energy trellis-coded modulation schemes with 2 states, necessary and suÆcient conditions to guarantee that a maximumlikelihood sequence estimator can decode each symbol with a xed delay of symbols are derived. Additive white Gaussian noise is assumed. MSK is a special case that belongs to the family of modulation schemes with = 1. It is shown that when these cond...
متن کاملPerformance Evaluation of Trellis-Coded Modulation Schemes
A description of the algorithms to evaluate the main parameters determining the pegormance of a Trellis-Coded Modulation (TCM) scheme is presented. TCM schemes are divided into classes that have an increasing degree of symmetry, so as to properly match the various algorithms to each class. The algorithms are compared in terms of computational complexity and tested on a set of multidimensional P...
