A communication system comprises a packet stream transforming unit, a mapping unit and a transmission unit. The packet stream transforming unit is configured to receive a 4-bit packet stream and transform the 4-bit packet stream into a 6-bit packet stream. The mapping unit is configured to map the 6-bit packet stream into multiple ternary bit streams, and the mapping unit maps at least one idle symbol into the ternary bit streams according to at least one particular bit of the at least one idle symbol of the 6-bit packet stream. The transmission unit is configured to transmit the ternary bit streams to a remote communication device through a cable.

Systems, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. Two Integrated Circuit (IC) devices may be collocated in an electronic apparatus and communicatively coupled through a 3-wire, 3-phase interface. A data transfer method operational on a first of the two or more devices includes determining presence of a misalignment of the 3-wire communication link involving two or more wires, and inverting a first bit of a 3-bit symbol encoded in a transition of signaling state of the 3-wire communication link when the misalignment of the 3-wire communication link is determined to affect phase relationships between two or more signals carried on the three wires, such that inverting the first bit corrects the phase relationships between the two or more signals. A version of the 3-phase signal may be communicated in a different phase state through each of three wires.

A data transmission and reception system may include: a data transmission apparatus configured to generate N Tx signals having discrete levels using N binary data, and output the N Tx signals to N single-ended signal lines, respectively, where N is a natural number equal to or larger than 2; and a data reception apparatus configured to receive the N Tx signals transmitted in parallel through the single-ended signal lines, and restore the N binary data by comparing the received N Tx signals to each other.

A differential detector for a receiver and a method of detecting the value of symbols of a signal is disclosed. In particular, a detector comprising: an analog to digital converter (110) for sampling samples (232) from symbols (234) of a signal (230); a differentiator (130) configured to differentiate the samples with a transfer function to produce a differentiated series of samples for each symbol; and a decision device configured to determine the value of each symbol by comparing values of the differentiated series of samples with boundary condition values.

A device and method for encoding bits to symbols for a communication system are described. In one embodiment, a method for encoding bits to symbols for a communication system includes receiving a set of N-bit data to be transmitted, where N is an integer, generating side scrambling values using a polynomial, scrambling the set of N-bit data using the side scrambling values to produce scrambled data, mapping the scrambled data to a particular set of M symbols from a plurality of sets of M symbols, where M is an integer and M is smaller than N, and outputting the particular set of M symbols for transmission over a transmission medium. Other embodiments are also described.
