摘要： A communication system is provided. A first communications device transmits at least one first message including predetermined bit sequences. A second communications device determines one or more antenna weighting vectors (AWVs) and one or more bitloading vectors (BLVs) by using the first message in accordance with a predetermined rule and transmits a second message including information pertinent to the AWVs and the BLVs to the first communications device. The first communications device further communicates with the second communications device about an AWV selected from the AWVs and the first and second communications devices apply the selected AWV to the corresponding antennas before exchanging data. The data includes a header carrying information pertinent to a BLV selected from the BLVs used to encode the data and a payload is transmitted to the second communications device. The second communications device decodes the data in accordance with the selected BLV.

摘要： A method is provided for sharing a communications channel in a wireless communications system. A network coordinating device of the wireless network obtains a first path quality information of each of a first set of one or more communications paths between a first pair of communications devices. The coordinating device also obtains a second path quality information of each of a second set of communications paths between a second pair of communications devices. The coordinating device then determines one or more co-existing communications paths based on the first and the second path quality information in accordance with a predetermined rule. Finally, the coordinating device sends channel resource allocation information to the first pair and the second pair of communications devices to use corresponding co-existing communications paths such that the first pair and the second pair of communications devices communicate over the communications channel during a period of time concurrently.

摘要： An approach for decoding a substantially orthogonal code, such as a CCK code, based on its trellis diagram is provided. Compared to the conventional decoder based on codeword correlation, the unconventional decoder here has the advantage that it can work together with a decision feedback equalizer without suffering from the error propagation effect of the equalizer. In other words, the unconventional decoder makes joint decision feedback equalizer and decoder workable, which in turn enables reliable transmission of a signal encoded by a substantially orthogonal code over a multi-path channel.
