A linear chip-level model for multi-antenna space-time coded wideband CDMA reconfigurable receivers

subject

description

Transmitter side reconfigurability is currently mostly implemented via adaptive modulation and coding. In the scenario of multiple antenna transmission which is foreseeable for fourth generation wireless mobile communications, a new level of reconfigurability might employ transmission scheme adaptation, i.e. dynamically switching between spatialmultiplex and space-time coded transmission. This paper presents a generalized linear model for the received signal in a multi-antenna CDMA signaling scheme on frequency-selective fading MIMO channels. The proposed model is unprecedented in that it supports general complex space-time codes as well as spatial-multiplex multiantenna transmission and it may be implemented with minor modifications to the front-end of a matched filter receiver
