    摘要: A device in a wireless network receives signals and determines media access control (MAC) slot boundaries of the received signals. The MAC slot boundaries are averaged in time, and a local slot boundary is modified in response thereto. The local MAC slot boundary is modified by less than ten percent of a short interframe space until the local MAC slot boundary is within one orthogonal frequency division multiplexing (OFDM) cyclic prefix duration of the averaged MAC slot boundaries.

    摘要: The present disclosure relates to variable-gain low noise amplifiers and RF receivers. An exemplary method for processing a RF signal provides a low noise amplifier with main and auxiliary amplifier modules. When a selection indicates the low noise amplifier operating in a high-gain mode, the main and auxiliary amplifier modules are coupled in parallel. When the selection indicates the low noise amplifier operating in a low-gain mode, the main and auxiliary amplifier modules are cross coupled. When a selection indicates the low noise amplifier operating in a moderate-gain mode, the auxiliary amplifier modules are disconnected from the main amplifier module.
