Coherent data communications technique |
摘要 |
A technique for communicating digital data through a noisy medium using phase modulated carrier signals. A multiphase clock drives parallel channels to sample the received signal, avoiding the need for a phase locked loop. Data is recovered from the noisy carrier by a two stage statistical filtering technique and pattern analysis of the filtered signals.
