Patent ID: 8111667

Claim:
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 Coding (STC) method, based on priority of said transmit data, wherein said SDM method distributes as a plurality of transmission streams, and transmits said transmit data, wherein said STC 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 STC method based on the priority of said transmit data and the transmission mode of said transmission mode table.
