Metadata
| Name: | Digital Receivers: Symbol-Timing Recovery for QPSK |
| ID: | m10485 |
| Language: | English (en) |
| Summary: | The goal of symbol-timing recovery is to sample message signals at the receiver for best performance. After the in-phase and quadrature signals pass through a matched filter, a delay-locked loop attempts to find the peaks in the output waveforms. |
| Subject: | Science and Technology |
| Keywords: | delay-locked loop, DSP, matched filter, noise, quadrature phase-shift keying, receiver |
