Abstract

This paper presents the implementation of Alamouti´s scheme on Polarizone´s Field Programmable Gate Array (FPGA)-based software defined radio platform and also to conduct experiment with RF transmission. A 16-QAM encoder is implemented in this project successfully. The system manages to encode incoming data to Alamouti codes by performing baseband signal processing and schedule its timing according to Alamouti encoding scheme. Detail design specification is presented and future enhancement for decoding and channel estimation is proposed.
