Abstract  Abstract

An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel.
