METHODS AND APPARATUS FOR LOW POWER OPERATION UTILIZING MULTIPLE ADCs WITH DIFFERENT PRECISIONS

摘要

An electronic device includes processing circuitry configured to detect a presence of a packet transmission via a channel, establish communication parameters and operational settings of an analog-to-digital conversion (ADC) operation using a training field (TF) of the packet if the packet comprises the TF, and utilize a channel estimation (CE) portion of the packet to perform channel estimation of the channel. The processing circuitry is also configured to utilize the channel estimates to compensate for distortions introduced by the channel with respect to portions of the packet subsequent to the CE portion, obtain a modulation order and coding scheme used for the data portion of the packet, select an analog-to-digital converter (ADC) to be used for a recovery of the data portion of the packet, and recover the information in the data portion of the packet using ADC output samples corresponding to the data portion of the packet.
