Method and apparatus for processing data for transmission in a multi-channel communication system using selective channel inversion

摘要

Techniques for determining a threshold used to select transmission channels for data transmission in a multi-channel communication system. According to these techniques, the threshold is determined by a number of steps, including defining a set of code rates, wherein each code rate is selectable for coding data prior to transmission, defining a set of setpoints, wherein each setpoint corresponds to a respective code rate and is indicative of a target signal-to-noise-plus-interference ratio (SNR) required at the corresponding code rate for a particular level of performance, determining a particular number of transmission channels supported by each code rate and capable of achieving the setpoint corresponding to the code rate, determining a performance criteria for each code rate based in part on the number of supported transmission channels, and selecting the threshold based on the determined performance criteria for the code rates in the set, wherein transmission channels are selected for use for data transmission based on the threshold.
