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： 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 method for determining isolation status of the RF repeater is provided. A modem in the repeater registers with a base transceiver station (BTS). Uplink output levels of a donor RF transceiver are calibrated and stored in the modem. The modem is synchronized to a BTS transmission received at the donor RF transceiver and the synchronization information is provided to a server RF transceiver of the repeater. Isolation detection and measurement can then be performed between donor transmit antenna and receive server antenna of the RF repeater and the automatic gain control parameter of donor RF transceiver and server RF transceiver are adjusted based upon the isolation detection and measurement value. The isolation and detection can be implemented in a co-processor coupled to the donor and server transceivers.

摘要： A wireless device comprises a transmitter chain receiving a transmit signal from a UE. The transmitter chain amplifies the transmit signal to produce an amplified transmit signal that is transmitted to a BS. A receiver chain receives a receive signal from the BS. The receiver chain amplifies the receive signal to produce an amplified receive signal which is transmitted to the UE. A second receiver chain receives a second receive signal from the BS. The second receiver chain amplifies the second receive signal to produce a second amplified receive signal that is transmitted to the UE. The gain of the transmitter chain, the receive gain and the second receive chain are balanced. The transmitter chain, the receiver chain, and the second receiver chain each comprise a transmit variable attenuator, with gains set by a controller.

摘要： A transmitter implements a method of transmitting data in a network. The transmitter encodes and transmits to a receiver a first transmission utilizing the first MCS level with a first quality level. The first quality level is higher than a prior quality level associated with the prior MCS level. The transmitter receives an indication that the transmission was received at the receiver with an error rate less than a first threshold. The transmitter encodes and transmits to the receiver a second transmission that is longer than the first transmission. The second transmission uses a second MCS level with a second quality level. The second quality level is between the prior quality level and the first quality level. The transmitter receives an indication that the transmission was received at the receiver with an error rate less than a second threshold. The transmitter utilizes the second MCS level to transmit data.

The infrastructure in-motion may be a base station or other infrastructure, and any or all of multiple techniques such as beam switching, beam selection, phased array, and null-steering, may be used to modify a transmission pattern. In various alternative embodiments, infrastructure in-motion in one geographical region establishes a first backhaul link with a first core network, moves to a second geographical region, and then establishes a second backhaul ink with a second core network.

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.
