1. A method of processing a plurality of Z vectors, each Z vector including Z elements, each element including K bits, where Z is a positive integer greater than 1 and K is a positive integer greater than zero, the plurality of Z vectors corresponding to a binary codeword, portions of said binary codeword having a direct mapping relationship to a plurality of transmission units, said plurality of Z vectors being stored in a set of D memory arrays, where D is an integer greater than zero, each memory array including Z rows of memory locations, each memory location of a row corresponding to a different array column, each array column corresponding to a different one of said plurality of Z vectors, each Z vector identifying one column in each of said D memory arrays, the method comprising: generating a series of sets of control information, each set of control information including: i) a transmission unit identifier; ii) a Z vector identifier; iii) a row identifier; and for at least one generated set of control information: reading P times K divided by D bits, where P is a positive integer greater than zero, from each column identified by the Z vector identified by the Z vector identifier included in said at least one generated set of control information.
