Abstract
A communication method includes: receiving input data at a transmitter, the transmitter including at least one convolutional encoder and at least one modulator; applying the input data to a trellis-coded modulation (TCM) scheme to encode the input data and produce one or more TCM symbols representing the encoded data; applying the one or more TCM symbols to a second modulation scheme, the second modulation scheme including a pulse modulation in combination with an additional modulation; and generating one or more modulation symbols representing the encoded data based on the second modulation scheme.
