Abstract:
1. A method for producing encoded trellis coded modulation (TCM) data from user information, the method comprising: determining a target information rate for the encoded TCM data; selecting one or more encoding parameters based on the determined target information rate, the one or more encoding parameters comprising a first dimensionality value for use during a first TCM processing interval and a second dimensionality value for use during a second TCM processing interval that occurs after the first TCM processing interval, wherein the first dimensionality value is different from the second dimensionality value; encoding a first number x1 of bits in a first portion of user information during the first TCM processing interval based, at least in part, on the first dimensionality value to produce a first number y1 of coded bits at a first rate x1/y1; encoding a second number x2 of bits in a second portion of the user information during the second TCM processing interval based, at least in part, on the second dimensionality value to produce a second number y2 of coded bits at a second rate x2/y2; and producing the encoded TCM data at a system output rate that is based on (x1+x2)/(y1+y2), wherein the system output rate is substantially equal to the target information rate.
