An equalizer includes: a channel estimator configured to generate a set of time-domain channel coefficients based on a receive signal; a frequency-domain transformer configured to generate a set of frequency-domain channel coefficients based on a frequency transform of the set of time-domain channel coefficients; an equalizer coefficient generator configured to generate a set of frequency-domain equalizer coefficients based on the set of frequency-domain channel coefficients; a time-domain transformer configured to generate a set of time-domain equalizer coefficients based on a time transform of the set of frequency-domain equalizer coefficients; and a filter configured to filter the receive signal based on a filter function that is based on the set of time-domain equalizer coefficients.

Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

A low cost millimeter wave receiver and method for operating same is disclosed. In one embodiment, the method comprises receiving the first signal, converting the first signal of the first bandwidth into an intermediate frequency band, splitting the converted first signal into N of intermediate signals, each having a bandwidth less than the digital processor bandwidth, wherein N is an integer greater than one, downconverting each of the N intermediate signals to the second frequency band, processing the downconverted plurality of signals with the digital processor to generate N processed signals, upconverting each of the N processed signals to the intermediate frequency band, converting the upconverted signals to the third frequency band, and transmitting the converted signals.
