Abstract

An apparatus and a method are provided. The apparatus includes a receiver configured to receive a signal over channels, a channel estimator configured to estimate the channels as first channel estimates; and a processor configured to compress the channel estimates to reduce buffer size. The method includes receiving a signal over channels by a receiver, estimating, by a channel estimator, the channels as a first channel estimate; and compressing, by a processor, the channel estimates to reduce buffer size.

Description

PRIORITY[0001]This application claims priority under 35 U.S.C. §119(e) to a U.S. Provisional Patent Application filed on Dec. 2, 2015 in the United States Patent and Trademark Office and assigned Ser. No. 62 / 262,072, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE DISCLOSURE[0002]Field of the Disclosure[0003]The present disclosure relates generally to an apparatus for and a method of channel estimation, and more particularly, to an apparatus for and a method of compressing channel estimates to reduce buffer size.[0004]Description of the Related Art[0005]A typical communication receiver using coherent detection has a channel estimation (CE) block that estimates various channel gains affecting a signal as it travels from a transmitter to a receiver. The coherent receiver uses CE for data demodulation. The channel estimates produced by this block are often stored in a CE output buffer to be used by other blocks (e.g. a symbol detector) in the receive...
