Abstract
A method, a device and a system for detecting channel quality are provided. The method includes: judging whether a Transmit Power Control (TPC) symbol output by a receiver is an invalid symbol; when the TPC symbol is a valid symbol, judging whether polarities of in-phase/quadrature (I/Q) components of the valid symbol are opposite to each other; counting the number of invalid symbols, the number of valid symbols, and the number of valid symbols with opposite polarities; and estimating a Bit Error Rate (BER) according to the number of the invalid symbols, the number of the valid symbols, and the number of the valid symbols with the opposite polarities, and detecting the channel quality through the BER.
