Abstract:
1. A method of processing a data stream for high speed wireless transmission between a transmitting unit and a receiving unit comprising the steps of: providing a data stream comprised of information bits and cyclic redundancy check (CRC) bits; encoding said data stream to generate first, second and third bit groupings comprised of first parity bits, second parity bits and systematic bits respectively; determining the number of bit storage locations available at said receiving unit; first rate matching said first, second and third bit groupings according to a selected pattern to provide modified first, second and third bit groupings such that the total number of bits in said modified first, second and third bit groupings is equal to said number of bit storage locations available at said unit; determining the number of transmission bits, said number of transmission bits equal to the total number of bits that can be transmitted during a single transmission frame of a transport channel; second rate matching said modified first , second and third bit groupings according to a selected set of parameters to identify first parity bits, second parity bits and systematic bits for generating a transmission stream comprised of selected ones of said identified bits having a total number of bits equal to said number of transmission bits.
