Abstract

Research has shown that significant degradation in performance can occur even when operating within the limits for carrier frequency and modulation index offsets permitted by the Bluetooth standard. This is even more severe for multi-bit detectors like the matched filter bank receiver, because such errors accumulate across a longer observation interval. This paper details the derivation of a stochastic gradient carrier frequency offset correction algorithm suitable for Bluetooth signals, as well as a separate algorithm applicable to the efficient realisation of the matched filter bank (MFB) receiver for Bluetooth signals. The reduced complexity MFB receiver for Bluetooth is described in our earlier publications.
