Description: 通过MATLAB软件;通过仿真得出性能曲线;从而比较bpsk的性能-The bit-error rate (BER) of binary phase-shift keying in Rayleigh fading, using the Alamouti transmission scheme and receiver selection diversity in the presence of channel-estimation error, is studied. Closed-form expressions for the BER of log-likelihood ratio selection, signal-to-noise ratio (SNR) selection, switchand- stay combining selection, and maximum ratio combining are derived in terms of the SNR and the cross-correlation coefficient of the channel gain and its corrupted estimate. Two new selection schemes, space–time sum-of-squares combining selection diversity and space–time sum-of-magnitudes selection diversity, are proposed and proven to provide almost the same performance as SNR selection, but with much simpler implementations. The effects of channel-

[Industry researchSpaceTimeBlockCoding

Description: This paper deals with the following issue in space time block coding (STBC) design: over a time selective channel,which scheme performs better, orthogonal STBC (O-STBC) or non-orthogonal STBC (NO-STBC)? It is shown that under time-selectiveness, once the vehicle speed has risen above certain value, NO-STBC always outperforms O-STBC - across the whole SNR range. Also, considering that all the existing NO-STBC schemes have been investigated under quasi-static channels only, a new simple receiver was derived for the NO-STBC system under time-selective channels.

Description: tgrr yggg ggg yttt Space time block coding (STBC) and beamforming techniques are two emerging technologies that can be employed at base station with multiple antenna to provide transmit diversity and beamforming gain to increase signal-to- noise ratio (SNR) of the downlink. STBC utilizes a diversity antenna system where the antenna spacing is usually required to be large enough, say 10 times wavelength of the carrier for a uniform linear array (ULA) in small angular spread environments, to obtain low-correlation/independent fading channels. While the beamforming antenna needs to achieve spatial directivity and the signals received at and/or transmitted from all antennas must be correlated or coherent. So the antenna spacing should usually be very small, e.g. half wavelength for ULA. -tgrr ygggggggggggg ytttttt Space time block coding (STBC) and beamforming techniques are two emerging technologies that can be employed at base station with multiple antenna to provide transmit diversity and beamforming gain to increase signal-to- noise ratio (SNR) of the downlink.

Description: 多输人多输出(MIMO)技术是第三代和未来移动通信与个人通信系统实现高数据速率,提高传输质量 的重要途径[1 ]。目前MIMO系统中使用的发射方案主要包括:①贝尔分层空时结构BI STA(Bell Layered Space Time Architecture)[。 ;②正交空时分组码OSTBC(Orthogonal Space Time Block Coding) ;⑧空时 格型编码STTC(Space Time Trellis Coding) 。-Motivated by the need for high throughput sphere decoding formultipleinput- multiple-output (MIMO) communication systems, we propose a parallel depth-first sphere decoding (PDSD) algorithm that provides the advantages of both parallel processing and rapid search space reduction. The PDSD algorithm is designed for efficient implementation on programmable multi-processor platforms. We investigate the trade-off between the throughput and computation overhead when the number of processing elements is 2, 4 and 8, for a 4× 4 16-QAM system across a wide range of SNR conditions. Through simulation, we show that PDSD can offer significant throughput improvement without incurring substantial computation overhead by selecting the appropriate number of processing elements according to specific SNR conditions.
