Performing Advanced Bit Manipulations Efficiently in General-Purpose Processors
This paper describes a new basis for the implementation of a shifter functional unit. We present a design based on the inverse butterfly and butterfly datapath circuits that perfo...

A MIMO channel perturbation analysis for robust bit loading
In narrowband multiple-input multiple-output (MIMO) communication systems, when the channel state information (CSI) is known perfectly at the transmitter and the receiver, techniq...

A Bit-Mapping Strategy for Joint Iterative Channel Estimation and Turbo-Decoding
Abstract— In this paper, we investigate Turbo-coded transmission over a temporally correlated flat Rayleigh fading channel. Conventionally, channel estimation is performed prior...
