Abstract :
Transmission diversity schemes have recently emerged in wireless systems as an attractive solution in order to mitigate fading effects. Space-time block codes (STBC) with two antennas can provide similar order diversity as maximal-ratio receiver combining (MARC). In this paper a transmit diversity scheme using STBC with two and four antennas is applied for the EDGE/EGPRS system and its results are evaluated in a interference-limited scenario. We jointly compare this strategy of multiple antennas with incremental redundancy (IR), a technique for link quality control (LQC) in EDGE.
