Frequency-domain space-time block coded single-carrier distributed antenna network
In this paper, space-time block coding (STBC) is applied to single-carrier distributed antenna network (SC-DAN). By using the frequency-domain STBC coded joint transmit/receive diversity (FDSTBC-JTRD) for the downlink while using the well-known frequencydomain space-time transmit diversity (FD-STTD) for the uplink, the diversity order is given by the product of the number of distributed antenna...
متن کاملCapacity of distributed antenna network by using single-carrier frequency domain adaptive antenna array
Single-carrier frequency domain adaptive antenna array (SC-FDAAA) has been proposed and proved in our previous study to be effective in suppressing multiple access interference in a severely frequency selective fading channel. In this paper, we studied the performance of SC-FDAAA in a distributed antenna network (DAN). To make it clear whether the performance of SC-FDAAA can benefit from the di...
متن کاملFrequency domain equalization space-time block-coded CDMA transmission system
In this work we propose a space-time block-coded (STBF) CDMA transmission system suitable for use with frequency domain equalization (FDE) algorithms. We illustrate the FDE by implementing the maximal ratio combining, the zero forcing and the minimum mean squared error single user detection algorithms. A diversity gain analysis is developed and some interesting results are pointed out. It is sh...
متن کاملFrequency-Domain Equalization Suitable for Single-Carrier Space-Frequency Block Coded Transmit Diversity in Frequency-Selective Fading Channel
が大きく劣化してしまうという問題がある. そこで本稿では,この問題を解決するために,TDD-SC-SFBC ダイバーシチのためのマルチサブキャリア FDE (MS-FDE)を提案する.提案法では,最小平均二乗誤差(MMSE)規範に基づき,1 符号語内のチャネルの周波数 変動を考慮して複数のサブキャリアの FDE 重みを同時に最適化することで,SFBC 符号の直交性の崩れに起因する 干渉を抑圧する.提案 MS-FDE を用いる TDD-SC-SFBC ダイバーシチを行った場合の平均 BER 特性を計算機シミュ レーションにより求め,MS-FDE は 1 符号語内でチャネルが周波数変動しないものと仮定して最適化された従来 FDE より常に優れた平均 BER 特性を達成できることを明らかにしている.また MB-FDE を用いる TDD-SC-STBC ダイバーシチとの特性比較を行い,TDD...
متن کاملFrequency-Domain Equalization for Single-Carrier Space-Time Block Coded Transmit Diversity in a High Mobility Environment
Single-carrier (SC) transmission with space-time block coded (STBC) transmit diversity can achieve good bit error rate (BER) performance. However, in a high mobility environment, the STBC codeword orthogonality is distorted and as consequence, the BER performance is degraded by the interference caused by the orthogonality distortion of STBC codeword. In this paper, we proposed a novel frequency...
