摘要: A method of estimating signal quality in a radio demodulator receiving an input stream symbols includes the steps sampling phase-only portion each stream, determining phase error for samples portions, and calculating estimate from plurality sample errors. The may be average magnitude predetermined number preamble, or data that follows.
