Wireless local area network receiver and associated method

摘要

A wireless local area network (WLAN) includes a server and receiver, which includes a radio frequency (RF) front-end circuit that receives wireless signals from the mobile nodes within the WLAN and detects baseband signals. A signal waveform detector edge detects a signal waveform and generates a trigger signal indicative of the modulation type, data format and time-of-arrival (TOA) information of a desired signal to be captured. A baseband processor receives the trigger signal from the signal waveform detector and captures the desired signal. A system controller is connected to the baseband processor and configures the baseband processor for processing the desired signal and obtaining message data and signal metrics that are transferred to the system controller to be communicated outbound from the receiver as a client to the server.

1. A wireless local area network (WLAN), comprising:
a server; a receiver in communication with said server as a network client, and comprising,
a radio frequency (RF) front-end circuit configured to receive wireless signals;a signal waveform detector connected to the RF front-end circuit and configured to detect one or more desired signal waveforms of the received wireless signal and, in response to detecting the one or more desired signal waveforms, generate a trigger signal indicative of a modulation type, a data format, and time-of-arrival (TOA) information; anda processor connected to the RF front-end circuit and the signal waveform detector configured to receive the trigger signal from the signal waveform detector and captures the one or more desired signal waveforms.
