Low Rate Error Correction Coding for Channels with Phase Jitter.

摘要

Many digital communication channels operating at low data rates suffer phase jitter and time varying frequency-offset effects which degrade the signal to noise ratio. Low rate error correction coding is shown to obviate this problem. Experimental results are presented for different low rate coding arrangements and the usefulness of the technique is discussed in relation to both coherent and non-coherent modulation methods.
