Abstract
A high-speed transmitter for digital data having a variable data rare, the transmitter comprising a convolutional encoder, adapted to generate, for each group of k input bits in a bitstream, n coded output bits, such that k and n are integers, n equal to or greater than k, and at least one of k and n is variable responsive to the variable data rate of the transmitter; and a modulator, coupled to map the output bits generated by the encoder to a constellation of M symbols for transmission by the transmitter, M an integer, which is variable responsive to the variable data rate of the transmitter; and wherein for a given rate Rs of transmission of the symbols by the transmitter, the variable data rate Rb is given by Rb=Rs*log(M)*Rc, wherein Rc is a code rate equal to k/n.
