Method and apparatus for the use of multiple-input, multiple output (MIMO) systems for multi-packet reception (MPR) |
摘要 |
A method for multipacket communication in an asynchronous wireless system includes the steps of transmitting at least two packets of 2M digital signals from a plurality of transmitters without other transmission taking place within a predetermined number of symbol durations from each side of each packet. Each transmitter generates digital signals denoted as at least two super-symbols according to an Alamouti coding scheme corresponding to M symbols of first set of super-symbols in a first transmission interval and a second set of super-symbols in a second transmission interval. The received packets include inter-symbol interference of the super-symbols when imperfectly synchronized which expands the time interval of the received packets. A symmetric Alamouti structure for the received packets is generated by folding the expanded received signal on itself, multiplying by a factor of -1, and decoding using the Alamouti structure for the received packets at each antenna of the receiver.
