    摘要： A communication system uses a differential edge modulation scheme having one of four or more values and a clock pulse is also encoded in each unit interval. A four-valued encoding may be as follows: prior to each unit interval, two signals are both at the same value; at the start of the unit interval, a first one of the signals is transitioned to indicate a first bit of the symbol; after a selected one of two delay periods that are less than the unit interval, the other signal to is transitioned indicate a second bit of the symbol; after this transition, both signals are again at the same value. The transitioning, at the start of the unit interval, provides an edge that may be extracted and used a timing reference.

    摘要： A communication system comprises a transmitter and a receiver that communicate differential phase modulated data over a wireline channel pair. The transmitter encodes data symbols by generating first and second data signals with differentially phase shifted signal transitions with respect to one another. The receiver receives the first data signal and the second data signal and samples the first data signal based on a signal transition timing of the second data signal to generate a first output data symbol. The receiver furthermore samples the second data signal based on signal transition timing of the first data signal to generate a second output data symbol.
