Abstract:
1. A wireless transmission repeater system comprising: a first wireless device having a transmitter for distributing transmission data including encoded data and a training signal to a plurality of antennas, and transmitting the data as radio signals from said plurality of antennas at a predetermined timing; a plurality of second wireless devices having repeaters each for receiving said radio signal, storing said radio signal into a buffer so that said radio signal is delayed by a predetermined time, and transmitting said radio signal delayed; and a third wireless device having a receiver for receiving and combining the radio signals from said plurality of second wireless devices or at least one of said second wireless devices and said first wireless device by a plurality of antennas and demodulating said encoded data by using said training signal multiplexed on the received radio signal and means for parallel-to-serial converting the radio signals received by the plurality of antennas of said third wireless device to combine the radio signals into encoded data, thereby obtaining reception data.
