Recently, in [8], the author investigated the performance of space-time trellis codes over LMS channels assuming the R-L model. Exact closed-form expressions for the average BER and/or SER of various binary and M-ary modulation schemes were derived in [4] over Rician-Nakagami fading channels.

Contrary to the traditional Nakagami model where η changes over the limited range of 5.0≥η, here ηvaries over the wider range of 0≥η[2]. I. As a consequence of the growing interest in land mobile satellite (LMS) systems, much effort is being devoted to the problem of modeling multipath fading and shadow fading in LMS channels.

Super-orthogonal space-time trellis codes have shown to outperform these codes, and also provide a systematic design method to maximize diversity and coding gain in quasi-static Rayleigh fading channels.
