摘要： A low-complexity optimal soft MIMO detector is provided for a general spatial multiplexing (SM) systems with two transmit and NR receive antennas. The computational complexity of the proposed scheme is independent from the operating signal-to-noise ratio (SNR) and grows linearly with the constellation order. It provides the optimal maximum likelihood (ML) solution through the introduction of an efficient Log-likelihood ratio (LLR) calculation method, avoiding the exhaustive search over all possible nodes. The intrinsic parallelism makes it an appropriate option for implementation on DSPs, FPGAs, or ASICs. In specific, this MIMO detection architecture is very suitable to be applied in WiMax receivers based on IEEE 802.16e/m in both downlink (subscriber station) and uplink (base station).

摘要： A single channel full duplex wireless communication system includes a processor, a transmitter, a receiver, a secondary transmission path, a combining element, a primary transmission feedback path and a secondary transmission feedback path. The transmitter transmits a transmission signal via a transmission path. The receiver receives a received signal via a reception path. The transmitter and the receiver utilize one channel to transmit and receive signals. The transmission signal causes self-interference. The processor estimates a first transfer function and feeds the secondary transmission path with the transmission signal adjusted by the first transfer function to reduce the transmission signal leaked to the reception path. The combining element combines the transmission signal with the adjusted secondary transmission path signal to remove the self-interference. The primary transmission feedback path output is modified by a second transfer function. The secondary transmission feedback path output is modified by a third transfer function.

摘要： Devices, systems, and methods are presented for a wireless base station to assign dynamically a plurality of radio transceiver chains among a varying number of wireless channels. In this manner, the communication system including the wireless base station may transition between a range extension mode and an enhanced capacity mode. In the range extension mode, a system is configured for maximum communication range with Subscriber Stations that are relatively distant from the radio transceiver chains, although communication is still possible with nearby Subscriber Stations. In the enhanced capacity mode, the system is configured for maximum communication throughput with Subscriber Stations that are relatively near to the radio transceiver chains, whereas communication with relatively distant Subscriber Stations will be either terminated or at least non-optimized.

摘要： A method for calibrating rates at which data is transmitted in a communication system. There is a short transmission utilizing a first set of communication parameters comprising first and second communication parameters. The first set of communication parameters are different from the second set of communication parameters used to create stable communication between the transmitter and receiver. The second set of communication parameters comprise first and second communication parameters. Then determining that there are substantially no errors associated with reception of the short transmission by the receiver. Then transmitting a long transmission utilizing a third set of communication parameters comprising first and second communication parameters. The first communication parameter of the third set is equal to the first communication parameter of the first set. The second communication parameter of the third set is equal to the second communication parameter of the second set.
