Abstract:
1. An apparatus for processing a channel estimation output in a wireless communication system, the apparatus comprising: an operation data generator for receiving a channel estimated data from a channel estimator, the channel estimated data comprising valid bits and extra bits, for searching the valid bits in the channel estimated data and for generating operation data by eliminating the extra bits from the channel estimated data; an operation processor for receiving the operation data, performing predetermined operation process for the operation data, and outputting a processed operation data; and a data restoration unit for receiving the processed operation data, and restoring the processed operation data to a restored data that has the same size as the channel estimated data, wherein the operation data comprises the valid bits, and indication information representing a start position of the valid bits, wherein the operation data further comprises a first sign bit identifying a start of first valid bits and the first valid bits, a second sign bit identifying a start of second valid bits and the second valid bits, and the indication information further representing respective start positions of the first valid bits and the second valid bits, and wherein the valid bits correspond to Channel Quality Information (CQI) and the extra bits correspond to information on changing a channel.
