20130022159 | METHOD AND APPARATUS FOR TRANSMITTING SIGNALS - A storage unit stores a preamble signal defined in a legacy system and a preamble signal defined in a MIMO system. A monitoring unit in a transmitting apparatus monitors the existence of any communication apparatus which is not compatible with the MIMO system but accepts the legacy system. A channel characteristics acquiring unit derives the characteristics of a radio channel between the transmitting apparatus and a receiving apparatus. A selector selects a packet format based on a monitoring result obtained by the monitoring unit. The selector also selects where to place LTS, based on the characteristics of wireless channel derived by the channel characteristics acquiring unit. | 01-24-2013 |
20120320851 | TRANSMITTING AND RECEIVING METHOD, AND RADIO APPARATUS UTILIZING THE SAME - A processing unit transmits, from at least one of a plurality of antennas, data corresponding respectively to the plurality of antennas. A control unit generates request signals with which to let a second radio apparatus supply information on rates at the second radio apparatus. When transmitting the request signal, the processing unit also transmits, from a plurality of antennas which includes antennas other than the antennas that transmit the data, known signals corresponding respectively to the plurality of antennas. | 12-20-2012 |
