Technique for switching between 1x and 2x oversampling rate in a TD-SCDMA receiver

摘要

A TD-SCDMA receiver is provided that includes a joint detection (JD) block receiving a first input signal from a channel estimation block for signal detection. A short channel detection (SCD) block receives the first input signal and detecting the presence/absence of an AGWN-like channel based on the first input signal from the channel estimation block. The SCD block switches the JD block between 1× and 2× oversampling rates by sending to the JD block a second input signal.
