Abstract: Systems and methods are disclosed for communicating on a pilot wire between Electric Vehicle Service Equipment (EVSE) and an Electric Vehicle (EV). In an example embodiment, a modem is coupled to the pilot wire that couples the EVSE and the EV. The modem transmits both pulse width modulation (PWM) command signals and power line communication (PLC) signals to a remote device via the pilot wire. The modem interleaves the PWM and PLC signals on the pilot wire so that latency requirements for the PWM signals are maintained. The modem supports parallel protocol stacks in which PLC signals are processed in a first path and PWM signals are processed in a second path that bypasses the first path and provides the PWM signals directly to a MAC layer. The modem may create a modified frame for the PLC signals to maintain the latency requirements.

Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts (11—1-11—4) that encode transport data; a mapping part (3304) that performs such a mapping that encoded data sequentially formed by the encoding parts (11—1-11—4) are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver (3301) that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.
