Forward error correction on multiplexed cdma channels enabling high performance coding

A method for providing wireless communication of digital signals being communicated digital signals between a plurality of wireless units (40) subscriber and a base (20) station being communicated digital signals using at least one radio frequency channel via radio signals modulated by code division multiple access, the digital signals also having a frequency of given nominal data, the method comprising the steps of: (a) making available a plurality of subchannels (31-1, 31-2,. .., 31-n) within each radio channel (30) of code division multiple access, in which the data rate of each channel (31) is less than the nominal data rate of the digital signals; (B) during the duration of a given connection between a unit (40) subscriber and a base station (20), allocate subchannels (31) available on a base as needed, with the number of subchannels (31) assigned changing so for the duration of a given connection; (C) dividing a picture (80) data segments (81) according to optimum segment sizes for each subchannel, sizes being selected segments to maximize the data throughput of the respective channels; (D) combining multiple segments into a combined block (85); (E) applying an encoding process forward error correction to combined block (85) to produce a block (86) with forward error correction; and (f) demultiplexing block (86) with forward error correction to divide it among the allocated subchannels (31) for the correction given.
