Power Allocation in Concatenated Trellis Coded Modulation
IEEE Transactions on Wireless Communications, 2008In this paper, power loading algorithms are presented for limited diversity fading channels with channel state information at the transmitter. Limited diversity channels are those that offer moderate levels of diversity (about 3-5) such as those encountered in orthogonal frequency division multiplexing (OFDM) based indoor wireless networks.

Decoding algorithms for noncoherent trellis coded modulation
IEEE Transactions on Communications, 1996Noncoherent decoding of trellis codes using multiple-symbol overlapped observations was shown previously to achieve close to the coherent performance. Optimal decoding by the Viterbi algorithm for L-symbol observations requires a number of states which grows exponentially with L.

Trellis-coded M-ary orthogonal modulation
Proceedings IEEE Symposium on Computers and Communications, 2002We have introduced the trellis-coded M-ary (M=32) 4-dimensional (4-D) orthogonal modulation scheme. Here, a rate 4/5 convolutional encoder generates one of 32 possible symbols every T seconds. Then the signal mapping for 32 symbols is performed by a M-ary 4-D orthogonal modulator.
