Space-Time Trellis Code Design Based on QAM-MTCM With Trellis Shaping
نویسندگان
چکیده
In this letter , super-orthogonal space-time trellis codes (SOSTTC) are extended for quadrature amplitude modulation (QAM) constellations. A systematic set-partitioning method for QAM constellations is given. Furthermore, trellis shaping based on set partitioning is incorporated in SOSTTC with QAM symbols to achieve extra shaping gain. Peak constraints can be used to limit the constellation expansion ratio and peak-to-average power ratio (PAPR).

On the Design of Space - Time CodesEmploying Multiple
| Space-time (ST) codes have shown considerable promise for reliable transmission, at relatively high data rates, over wireless fading channels in systems employing multiple transmit and receive antennas. Here, we consider the design of space-time codes employing multiple trellis coded modulation (MTCM). In MTCM, each trellis branch corresponds to multiple symbol transmissions from each transmi...
متن کاملSystematic design of space-time codes employing multiple trellis coded modulation
The design of space-time (ST) codes employing multiple trellis coded modulation (MTCM) is considered. This structure is shown to be necessary for achieving maximum transmit diversity gain when using trellis codes with parallel paths. Systematic code search procedures with low complexity are described based on the properties of ST-MTCM codes. It is illustrated that, if the trellis branches are p...
متن کاملA Rank Criterion for Qam Space-time Codes with Application to Turbo Coding
SufJicient conditions to ensure QAM space-time codes achieve full space diversity in quasi-static fading channel are presented. The conditions are on code words or generator matrices instead of on every code word pair. This simpl@es the check of full space diversity of a code. Based on these conditions, full space diversity parallel concatenated turbo codes are proposed to use in a multiple ele...

This paper proposes high-rate full-diversity spacefrequency trellis code (SFTC) designs, which achieve the full diversity advantage at high transmission rate, for frequency selective fading channels. The proposed SFTC are derived based on the concept of concatenated space-time block code (STBC) and multiple trellis coded modulation (MTCM) encoder constructions. The existing SFTC designs only pr...

In this paper, a performance evaluation of a multiple trellis coded modulation (MTCM) waveform is proposed for mobile channel environments. In order to reduce received SNR in BER 1.0E-6 conditions, we proposed a 32 trellis coded modulation (TCM). We also applied orthogonal frequency division multiplexing (OFDM) technologies such as timing recovery, carrier recovery, and equalizer, in order to r...
