摘要： A multiple access digital communication method in ultra-wideband (UWB) radio access network is provided. More specifically, a multiple access technique in UWB communication channels is provided where UWB communication channels can be more efficiently used and collisions between multiple access user nodes can be more effectively avoided when the channels have a great multiple path fading. The digital communication method for use in an uplink in a UWB communication system includes the steps of: receiving data symbols from respective nodes, in which the data symbols are transmitted according to respective orthogonal time hopping patterns; checking whether there is a collision of the orthogonal time hopping patterns; and decoding the data symbols depending on whether data symbols of nodes involved in the collision of the orthogonal time hopping patterns are the same.

摘要： A Multiple-Input Multiple-Output data transmission system includes access stations and an access point having multiple receive antennas. An access point has a minimum contention window size decision unit to determine a minimum contention window size based on the number of receive antennas and a number of access stations, a broadcasting unit to broadcast the determined minimum contention window size to the access stations, and a receiver to receive data from the access stations in a contention window that is calculated based on the minimum contention window size. An access station receives the minimum contention window size from the access point, determines a first contention window size based on the minimum contention window size, and transmits data to the access point within the first contention window. If the transmission fails, the access station determines a second contention window size and retransmits the data in the second contention window.

摘要： A scheduler and scheduling method that may select a data transmission time interval and a data transmitting station are included in a multi-user Multiple Input Multiple Output (MIMO) communication system. An access point may include a receiver to receive channel measurement signals from stations using a plurality of receive antennas; a channel estimation unit to generate channel state matrices with respect to wireless channels formed from the stations to the receive antennas using the channel measurement signals; and a scheduler to select at least one transmitting station from the stations by considering the channel state matrices and a number of the receive antennas. The receiver may receive a data stream from the selected transmitting stations. Stations receive identifiers corresponding to transmitting stations and/or transmitting antennas to identify stations or antennas for transmitting data streams to the access point.

摘要： A multiple-input multiple-output (MIMO) wireless local area network (WLAN) system includes a method for transmitting and receiving data using a MIMO decoding scheme. A method for receiving data includes receiving a preamble from one or more stations via a plurality of receiving antennas, estimating a wireless channel between the station and an access point based on the received preambles, detecting a collision associated with each station based on the received preambles, and decoding the data by referring to a wireless channel estimate if the collision is detected.
