Abstract:
A method for encoding a digital communication channel using a convolutional encoding and interleaving technique for enhancing the performance of a digital communication, comprising the steps of: (a) storing a frame data, which is inputted for a channel encoding operation, into encoder RAMs ERAM0 and ERAM1 via a demultiplexer selected at a predetermined period of the frame; (b) addressing the ERAMs and storing the data into register via a multiplexer in accordance with a control of a frame selection signal; (c) addressing the ERAMs for reading the previous data which is read and storing the read data into the register; (d) selecting an input data among two register output data, inputting the selected input data into the convolutional encoder and generating a code symbol; and (e) selecting one among the code symbols and obtaining an output of the channel encoder that completed the convolutional encoding and interleaving operations.
