Multiple trellis coded frequency and phase modulation
Multiple trellb coded modulation of constant envelope frequency and phaqe modulated signal sets (MTCM/FPM) is investigated for performance on the AWGN channel and on the one-sided normal, Rayleighand Rician-fading channels. The Nakagami-m fading model is wed as an alternative to the Ricianfading model to calciilate the error probability upper bound for trellis coded schemes on the fading channe...
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 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 کاملStaggered Trellis Coded Modulation
A special construction method for parallel concatenated trellis coded modulation, namely staggered trellis coded modulation, is presented. This coding scheme is similar to that of the recently introduced binary laminated turbo codes and it comprises a convolutional structure due to an additional block-wise memory. The encoder and a possible decoder for this new code construction is presented an...
متن کاملMultidimensional trellis coded phase modulation using a multilevel concatenation approach. I. Code design
-The first part of this paper presents a simple and systematic technique for constructing multidimensional M-ary phase shift keying (MPSK) trellis coded modulation (TCM) codes. The construction is based on a multilevel concatenation approach, in which binary convohitionai codes with good free branch distances are used as the outer codes and block MPSK modulation codes are used as the inner code...
