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 spatial-multiplex and space-time coded transmission. This paper presents a generalized linear model for the re-ceived signal in a multi-antenna CDMA signaling scheme on frequency-selective fading MIMO channels. The pro-posed model is unprecedented in that it supports general complex space-time codes as well as spatial-multiplex multi-antenna transmission and it may be implemented with minor modifications to the front-end of a matched filter receiver.

Abstract
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 spatial-multiplex and space-time coded transmission. This paper presents a generalized linear model for the re-ceived signal in a multi-antenna CDMA signaling scheme on frequency-selective fading MIMO channels. The pro-posed model is unprecedented in that it supports general complex space-time codes as well as spatial-multiplex multi-antenna transmission and it may be implemented with minor modifications to the front-end of a matched filter receiver.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
