| Jul 2, 2016 at 23:05 | comment | added | Dan Boschen | It is common to see two (or more) samples per symbol due to pulse-shaping and managing frequency offsets between transmitter and receiver. With pulse shaping considerations alone, you will have some excess bandwidth, so one sample per symbol will not be sufficient. Common carrier tracking and timing recovery techniques (such as the Gardner Timing Error Detector) require 2 samples per symbol. | |
