Title: LOW-COMPLEXITY HIGH-PERFORMANCE GFSK RECEIVER WITH CARRIER FREQUENCY OFFSET CORRECTION
Authors: Charles Tibenderana; University of Southampton

Abstract: This paper presents an implementation of a GFSK receiver based on matched filtering of a sequence of K successive bits. This enables improved detection and superior BER performance but requires 2^K matched filters of considerable complexity. Exploiting redundancy by performing phase propagation of successive single-bit stages, we propose an efficient receiver implementation. Results presented highlight the benefits of proposed method in terms of computational cost and performance compared to the standard methods. We also address carrier frequency offset, and suggest a blind algorithm for its elimination. Performance results are exemplarily shown for a Bluetooth system.
