An aspect of the present disclosure includes methods, systems, and computer-readable media for triggering the single signal during the first buffer period to concurrently adjust a first plurality of gain states of a first plurality of low-noise amplifiers associated with a first expected reception of the first symbol on the first component carrier and a second plurality of gain states of a second plurality of low-noise amplifiers associated with a second expected reception of the second symbol on the second component carrier, and receiving the first symbol via the first component carrier and the second symbol via the second component carrier after the first buffer period.

Methods and apparatus for dynamic adjustment of amplifier gain

A communications device and receiver system and method to efficiently distribute functions among radio frequency (RF), analog front end (AFE) and baseband modules for ultra-low power consumption comprising a wideband receiver subsystem selectively coupled to a signal input receiving a first frequency band, a narrowband received subsystem selectively coupled to the signal input receiving a second frequency band and, a controller configured to monitor the first frequency band using the first receiver subsystem and if a wake up signal is detected using the first receiver subsystem, connect the second receiver subsystem to the signal input and tune the second receiver subsystem to a channel transmitting the wake up signal, the wake up signal including channel selection information defining the channel for subsequent communications. Wherein, the two frequency bands overlap and center on different frequencies.

Low-power narrow and wide band receiver system

A method for determining an overlap and add length estimate comprises determining a plurality of correlation values of a plurality of ordered frequency domain samples obtained from a data frame; comparing the correlation values of a first subset of the samples to a first predetermined threshold to determine a first edge sample; comparing the correlation values of a second subset of the samples to a second predetermined threshold to determine a second edge sample; using the first and second edge samples to determine an overlap and add length estimate; and providing the overlap and add length estimate to an overlap and add circuit.

System and method for adaptive overlap and add length estimation

Phase tracking in an OFDM symbol comprises determining a sufficient statistic for CFO and SFO estimation from a differential metric between a current OFDM symbol and a previous OFDM symbol transmitted on the same frequency band. The sufficient statistics corresponding to positive pilot tones are combined with those corresponding to negative pilot tones to estimate the CFO and SFO.
