QPSK Signal Timing Offset Correction

Correct a fixed symbol timing offset on a noisy QPSK signal by using the Symbol Synchronizer block.

Explore Model

The Delay block adds a fixed timing error of 2 samples to the signal at the Raised Cosine Transmit Filter output. Since the Raised Cosine Transmit Filter configuration outputs 4 samples per symbol, the timing delay is 0.5 symbols.
