Serial code format optimized for remote control applications over noisy communications channel |
摘要 |
A transmitted data stream in a remote control system is a serial data stream having a synchronization sequence and a data sequence. The data sequence is encoded into a symbol comprised of a series of data bits wherein a 110 may represent a logic 1 and a 011 may represent a logic 0. A self adaptive filter adjusts its gain and offset to determine the duration of one bit. Providing a serial code format wherein the synchronization sequence has a smiller duty cycle as the duty cycle of a symbol aids the self adaptive filter to set its threshold switching level accurately and quickly, thus aiding the receiver to decode the transmitted data stream.
