Implementation of Space Time Block Codes for Wimax Applications
The proposed system implementation is developed on an existing MIMO Smart Antenna Software RAdio Test System (SASRATS) platform, designed to test and verify various space time architectures and algorithms. The4 receivers complement a 4-transmitter Space Time (ST) encoding platform designed and developed for real-time testing of ST coding schemes developed by Alamouti and others mentioned. The primary objective is to increase system capacity and performance through the use of multiple antennas, employing spatial multiplexing and ST coding and decoding. Spatial multiplexing and diversity techniques are currently adopted in the IEEE 802.11n draft specification to fully exploit the benefit of MIMO channels.
