摘要： Throughput conditions limited by multiplicative noise may be improved by distributing a transmission power across MIMO data streams communicated between MIMO communication nodes. In particular, the transmission power is distributed based on knowledge at the transmitter of the MIMO channel to decrease the transmission power allocated to one or more of the data streams associated with a dominant signal path relative to the transmission power allocated to one or more data streams associated with a weaker signal path to increase at least one of a quality and a throughput condition of the MIMO channel.

摘要： The method and apparatus disclosed herein improve throughput conditions limited by multiplicative noise by determining precoder weights for each data stream communicated between a MIMO transmitter node and a MIMO receiver node. The precoder weights are determined based on information derived from non-precoded reference symbols to decrease the energy allocated to the dominant signal path relative to the energy allocated to the non-dominant signal paths.

摘要： The invention relates to a wireless outdoor-indoor multiple-input multiple-output (MIMO) communications system for communicating with user equipment located inside a physical structure such as a building. The MIMO communication system is comprised of a node having at least two node antennas, wherein the node is configured for line of sight (LOS) wireless MIMO communication with at least two outdoor-indoor repeaters, and of at least two outdoor-indoor repeaters adapted for LOS wireless MIMO communication with the node. The repeaters have at least one repeater antenna each, provided outside the physical structure, for LOS MIMO communication with the node and at least two DASs each, provided inside the physical structure, for indoor MIMO communication with the user equipment located inside the physical structure. The repeaters are provided outside on the same physical structure and spaced well-apart, and each DAS of each repeater is provided such that they provide the same indoor coverage of the same interior space in the physical structure.

摘要： A system and method for suppressing disturbance signal components in a communication signal is disclosed. The system and method utilize a priori information about the fundamental frequency of the disturbance signal component to generate an estimate of the disturbance signal component. This estimated disturbance signal may be subtracted from the communication signal to suppress the disturbance signal component in the communication signal.
