In the context of wireless communication, a Multiple-Input Multiple-Output (MIMO) system is a system that employs multiple antennas both at the transmitter and receiver. The first theoretical analysis of MIMO systems were developed by Winters (1987), Foschini (1996) and Telatar (1999), and since then there have been many research efforts on this subject. What mainly makes MIMO systems interesting is their potential ability to achieve an increase in system capacity or in link reliability without requiring additional transmission power or bandwidth (Goldsmith, 2005). In this work, we focus on the utilization of MIMO systems for the lossy transmission of source information. In particular, we want to compare several different strategies for the transmission of a zero mean Gaussian source over Rayleigh-fading MIMO channels, assuming rate-adaptive source encoding. The MIMO transmission strategies are based on techniques such as Repetition coding (REP), Time Sharing (TS), the Alamouti scheme (ALM) and Spatial Multiplexing (SM) (Alamouti, 1998; Tse & Viswanath, 2006).

Abstract
In the context of wireless communication, a Multiple-Input Multiple-Output (MIMO) system is a system that employs multiple antennas both at the transmitter and receiver. The first theoretical analysis of MIMO systems were developed by Winters (1987), Foschini (1996) and Telatar (1999), and since then there have been many research efforts on this subject. What mainly makes MIMO systems interesting is their potential ability to achieve an increase in system capacity or in link reliability without requiring additional transmission power or bandwidth (Goldsmith, 2005). In this work, we focus on the utilization of MIMO systems for the lossy transmission of source information. In particular, we want to compare several different strategies for the transmission of a zero mean Gaussian source over Rayleigh-fading MIMO channels, assuming rate-adaptive source encoding. The MIMO transmission strategies are based on techniques such as Repetition coding (REP), Time Sharing (TS), the Alamouti scheme (ALM) and Spatial Multiplexing (SM) (Alamouti, 1998; Tse & Viswanath, 2006).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
