Improved Matching-Pursuit Implementation for LTE Channel Estimation

In English

Författare

Summary, in English

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 use of available resources. The design is implemented in a 65 nm low power process from STMicroelectronics. It is 1 mm2, including input pads and extra control logic. The estimator shows great improvement in speed compared to prior art, allowing 8 times the number of updates in the available time. This is due to both algorithm advancements and implementation techniques. Power consumption of the estimator is simulated to 14.3 mW, running at 50 MHz.
