Frequency-Domain Receivers for Rate-1 Space-Time Block Codes
Silva, Mário Marques da; Dinis, Rui; Correia, Américo M.C.This paper considers iterative frequency-domain receivers for block transmission techniques with rate-1 Space Time Block Coding (STBC) for two and four transmit antennas using both Orthogonal Frequency Division Multiplexing (OFDM) and Single-Carrier (SC) schemes. The proposed receiver includes an interference canceller which enhances the performance of the non-orthogonal STBC scheme with 4 transmit antennas, a...
On transmission techniques for multi-antenna W-CDMA systems
Silva, Mário Marques da; Correia, Américo M. C.; Dinis, RuiIn this paper we present and evaluate a new pre-processing scheme for Multiple Input Multiple Output (MIMO) channels. Its performance is compared with other MIMO schemes proposed for the downlink of Wideband-Code Division Multiple Access (W-CDMA) systems, namely a variation of the Beam Forming (BF), entitled Beam-Selective Transmit Diversity (BSTD) or post-processing schemes, such as the Alamouti-like MIMO or t...
Interference Suppression Consisting of Pre-Distortion Filtering and Selective T...
Silva, Mário Marques da; Correia, Américo M. C.; Dinis, RuiIn this paper we present and evaluate a pre-distortion (PD) scheme for the downlink of Wideband-code division multiple access (W-CDMA) systems considering a Rake in the receiver in order to exploit multipath diversity. Its performance is compared with schemes without the PD at the base station (BS), and combined with a transmit diversity (TD) scheme to improve the performance by exploiting spatial diversity. It...
