چکیده

Abst rac t -The Canadian mobile satellite (MSAT) channel has been modelled as the sum of lognormal and Rayleigh components to represent foliage attenuation and multipath fading, respectively. Several authors have applied trellis coded modulation (TCM) schemes to this channel, estimating the bit error performance via computer simulation. In this paper, a general expression is presented for the pairwise error probability (PEP) of TCM schemes transmitted over this channel under ideal interleaving. The expression can be specialized to several cases including ideal coherent detection, pilot-tone aided detection, and differential detection. The results are substantiated by means of computer simulation.

Evaluation of the Exact Union Bound for Trellis-Coded Modulations Over Fading Channels - Communications, IEEE Transactions on

-An analytical technique is presented for computing the exact union bound on the average bit error probability of trellis coded modulation schemes over Rayleigh, Rician, or shadowed Rician-fading channels. To this end, an integral expression is derived fior the painvise error event probability (PEP). Existing bounds can be obtained as special cases of this expression. It turns out that a Gauss-...

Performance of 4- and 8-state TCM schemes with asymmetric 8-PSK in fading channels

For Rayleigh fading channels, Ricean fading channels with a small parameter and shadowed Rician channels with the code design criteria are to maximize the effective length as well as the minimum product distance of the code. In this paper, we use two different asymmetric 8-PSK signal sets in 4-state and 8-state rate 2/3 trellis-coded modulation (TCM) schemes and show performance gain over TCM s...

Error Performance of MPSK Trellis-Coded Modulation over Nonindependent Rician Fading Channels

This paper presents new upper bounds on the pairwise error probability (PEP) of trellis-coded modulation (TCM) schemes over nonindependent Rician fading channels. Cases considered are coherent and pilot-tone-aided detection and differential detection of trellis-coded multilevel phase-shift keying (TC-MPSK) systems. The average bit-error probability Pb can be approximated by truncating the union...

Upper Bounds on the BER Performance of MTCM-STBC Schemes over Shadowed Rician Fading Channels

Space-time block coding (STBC) provides substantial diversity advantages with a low decoding complexity. However, these codes are not designed to achieve coding gains. Outer codes should be concatenated with STBC to provide additional coding gain. In this paper, we analyze the performance of concatenated trellis-coded STBC schemes over shadowed Rician frequency-flat fading channels. We derive a...
