Improved Matching-Pursuit Implementation for LTE Channel Estimation
In this paper an implementation of a reduced complexity matching pursuit channel estimator for LTE is presented. The design contains an FFT/IFFT module with non-radix 2 units and the core estimator. The FFT/IFFT module is flexible enough to perform both operations using the same hardware. Based on prior work the needed internal word lengths are found. Internal shifts are employed to maximize the u
