SPATIAL MULTIPLEXING WIRELESS TRANSMISSION SYSTEM, SPATIAL MULTIPLEXING WIRELESS TRANSMISSION METHOD, AND COMPUTER PROGRAM

Document Type and Number:

WIPO Patent Application WO/2011/105500

Kind Code:

A1

Abstract:

The spatial multiplexing wireless transmission system is configured from multiple terminal stations provided with a base station and multiple antennas. The base station is provided with an information signal generation unit, a control signal generation unit, a transmission frame generation unit, multiple beam forming units, a sending and receiving switching unit, a received signal processing unit, a propagation environment estimation unit, and an antenna information generation unit. At least one terminal station is provided with a sending and receiving switching unit, a received signal processing unit, a decoding unit, an antenna information extraction unit, an antenna information generation unit, a transmission unit, a battery, a remaining battery power detection unit, a transmission request extraction unit, and a propagation environment estimation unit.
