ABSTRACT:
In a MIMO wireless transceiver, priority control that judges priority of transmit data and a transmission mode table are provided to control an option as to which transmission system SDM or STBC is selected, coding rate and modulation method based on a transmission mode for a transmission destination that is determined by priority of transmission data and status of a communication matrix at the time of data transmission.With such arrangement, a wireless communication system composed of the MIMO wireless transceiver can control coding, MIMO signal processing and modulation methods according to priority of transmit data. More specifically, it is possible to ensure transmission of data having higher priority and improve throughput in total when a plurality of types of data are transmitted.
