摘要： The present invention discloses an adaptive parameter adjustment method for a hybrid precoding millimeter-wave transmission system. The method includes the following step: interacting between a transmitter and a receiver for a number of radio frequency chains that need to be established. The receiver calculates, according to a received signal power at the time of established a different number of radio frequency chains and a total power consumption at the time of established the different number of radio frequency chains, the number of the radio frequency chains that need to be established. According to the present invention, under a condition of balancing power consumption and a rate, a number of radio frequency chains that need to be established is adaptively selected, so as to optimally configure power consumption and a transmission rate in a millimeter-wave transmission system.

摘要： An access node of a communication system is configured to control crosstalk between channels of the system. Vectoring circuitry in the access node estimates crosstalk between channels of the system, generates a compensation matrix based on the crosstalk estimates, and generates compensated signals based on the compensation matrix. The compensation matrix, which may be a precoder matrix or a postcoder matrix, is generated using a multiplicative update process in which a previous version of the compensation matrix comprising one or more non-zero off-diagonal elements is updated by at least one of pre-multiplying by a first auxiliary matrix and post-multiplying by a second auxiliary matrix, with a given one of the auxiliary matrices also comprising one or more non-zero off-diagonal elements. The compensated signals may be pre-compensated signals or post-compensated signals.

摘要： Embodiments of a wireless communication system and methods for cancelling echo signals in the system are generally described herein. Some of these embodiments include phase shifters to generate output signals, each having a phase shift relative to a transmitted signal, a attenuator unit to attenuate the output signal of each of the phase shifters based on weights to generate attenuated signals, each corresponding to the output signal of one of the phase shifters, a weight calculator to perform an operation for selecting values for the weights without using components associated with the transmitted signal as inputs for calculating the values for the weights, and at least one summer to sum the attenuated signals and a received signal containing an echo signal to generate an echo-canceled signal.

摘要： A method in anode for achieving Radio Frequency, RF, requirement levels across a set of RF transceivers of a base station, wherein the set of RF transceivers generates one or more Multiple-Input Multiple-Out-put, MIMO, branches. The node groups (606) the one or more MIMO branches into groups of MIMO branches, wherein the one or more MIMO branches in each group of MIMO branches are generated from the same set of RF transceivers. The node generates a combined requirement level by combining (607) a per MIMO branch RF requirements level for the MIMO branches in the group of MIMO branches using a combining function. The node distributes (609) the combined requirement level into a respective individual RF requirement level for each of the respective RF transceivers according to a distribution function.
