Beam Pattern Scanning (BPS) versus Space-Time Block Coding (STBC) and Space-Time Trellis Coding (STTC)
In this paper, Beam Pattern Scanning (BPS), a transmit diversity technique, is compared with two well known transmit diversity techniques, space-time block coding (STBC) and space-time trellis coding (STTC). In BPS (also called beam pattern oscillation), controlled time varying weight vectors are applied to the antenna array elements mounted at the base station (BS). This creates a small moveme...
متن کاملSingle-Carrier Space-Time Trellis and Space-Time Block Coding for Dispersive Rayleigh Fading Channels
In this contribution we propose a novel Space-Time Coding (STC) scheme for transmissions over dispersive Rayleigh fading channels, which invokes a Joint-Detection assisted Minimum Mean Square Error based Decision Feedback Equalizer (JD-MMSE-DFE) for jointly detecting the channel-impaired wideband signals of multiple transmit antennas. The performance of the proposed scheme was investigated usin...
متن کاملSpace-time block coded adaptive modulation aided OFDM
Space-time block codes provide substantial diversity advantages for multiple transmit antenna systems at a low decoding complexity. In this contribution, we investigate the achievable diversity advantages in the context of adaptive modulation aided turbo coded OFDM. The two-transmitter, one-receiver G2 block space-time coded scheme using no channel coding or gradually increasing rate turbo codi...
متن کاملConcatenated space-time block coding with trellis coded modulation in fading channels
Trellis coded modulation (TCM) is a bandwidth efficient transmission scheme that can achieve high coding gain by integrating coding and modulation. This paper presents an analytical expression for the error event probability of concatenated space–time block coding with TCM which reveals some dominant factors affecting the system performance over slow fading channels when perfect interleavers ar...
متن کاملSpace-time block codes versus space-time trellis codes
Transmit diversity schemes for the coherent multiple-antenna flat-fading channel range from spacetime block codes (STBC) to space-time trellis codes (STTC). In this letter we compare the performance of STBC and STTC by means of frame error rate. We discover that a simple concatenation of STBC with traditional AWGN (additive white Gaussian noise) trellis codes outperforms some of the best known ...
