Bandwidth-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 کاملPunctured Trellis-Coded Modulation
THIS PAPER IS ELIGIBLE FOR THE STUDENT PAPER AWARD In classic trellis-coded modulation (TCM) signal constellations of twice the cardinality are applied when compared to an uncoded transmission enabling transmission of one bit of redundancy per PAM-symbol, i.e., rates of K K+1 when 2 denotes the cardinality of the signal constellation. In order to support different rates, multi-dimensional (i.e....
متن کاملBandwidth-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 کاملIterative Decoding of Serially Concatenated Punctured Trellis-Coded Modulation
Iterative decoding of serially concatenated code is extended to punctured trellis-coded modulation. A system configuration, a decoding algorithm and a performance evaluation method are proposed. It realizes a total coding rate of m/(m+1) by puncturing parity bits. Simulation results indicate that the proposed system shows no flattening effect which is observed in parallel concatenated system an...
