A Low-Cost Scalable Matched Filter Bank Receiver for GFSK Signals with Carrier Frequency and Modulation Index Offset Compensation

A Low-Cost Scalable Matched Filter Bank Receiver for GFSK Signals with Carrier Frequency and Modulation Index Offset Compensation
This paper addresses a low-cost matched filter bank (MFB) receiver for GFSK signals with estimation and correction of carrier frequency and modulation index offsets, such as found in Bluetooth systems. The proposed MFB implementation exploits redundancies in an otherwise prohibitively large system of filter banks by performing matched filtering over a symbol period followed by an iterative process of phase propagation. The resulting scheme has low complexity, is scalable, and permits the estimation of carrier frequency and modulation index offsets from the intermediate MFB outputs. We present simulations and a comparison of the proposed system for a Bluetooth scenario.

Abstract

This paper addresses a low-cost matched filter bank (MFB) receiver for GFSK signals with estimation and correction of carrier frequency and modulation index offsets, such as found in Bluetooth systems. The proposed MFB implementation exploits redundancies in an otherwise prohibitively large system of filter banks by performing matched filtering over a symbol period followed by an iterative process of phase propagation. The resulting scheme has low complexity, is scalable, and permits the estimation of carrier frequency and modulation index offsets from the intermediate MFB outputs. We present simulations and a comparison of the proposed system for a Bluetooth scenario.
