Abstract:
1. A wireless transceiver which executes transmission and reception of data wirelessly by using at least two antennas, said wireless transceiver comprising: a priority control unit which judges priority of transmit data, said priority being predetermined; and a transmission mode table in which an identifier that uniquely identifies a transmission destination is associated with a transmission mode that indicates channel status of transmission matrix of a communication destination for each said transmission destination, wherein a switching is made between a Space Division Multiplexing (SDM) method and a Space Time Blocking Coding (STBC) method, based on priority of said transmit data, wherein the (SDM) method distributes as a plurality of transmission streams, and transmits said transmit data, wherein said (STBC) method performs time-space encoding on said transmit data, and wherein, when data is transmitted to a transmission destination identified by said identifier, a switching is made between said (SDM) method and said (STBC) method based on the priority of said transmit data and the transmission mode of said transmission mode table.
