Abstract:
1. A multi-antenna system for a SDR (Software Defined Radio) system comprising: an RF/IF subsystem coupled to a multi-antenna; a modem subsystem comprising a multiple access processing unit configured to process a signal received from the RF/IF subsystem and extract a desired user signal from the signal, a channel separator configured to separate a pilot channel from the desired user signal and a pilot separator configured to extract a pilot signal from the pilot channel; and a multi-antenna subsystem configured to execute multi-antenna algorithm with the RF/IF subsystem and modem subsystem, wherein the multi-antenna subsystem includes: an algorithm executing unit configured to execute the multi-antenna algorithm on the signal received from the RF/IF subsystem by using the pilot signal; a synchronization unit configured to estimate frame and symbol timing of the multi-antenna system; and a control unit configured to control the algorithm executing unit and the synchronization unit.
