Abstract

The Bluetooth standard has a lax specification for parameters such a carrier frequency and modulation index. Research has shown that significant system degradation can occur even when operating within the permitted limits. Hence, a high-integrity Bluetooth receiver will need to compensate for this mismatch. Where multipath propagation exists, it will undermine parameter synchronising algorithms, and taking into account the limited burst lengths of Bluetooth packets, it is essential that equalisation occurs fast enough so as to give algorithms downstream sufficient time to converge, and minimise information loss. The coloured nature of Bluetooth signals and the possibility of a carrier frequency offsets, limit the choice of equaliser algorithms that can guarantee fast convergence. As a remedy, in this paper we propose the normalised sliding window constant modulus algorithm (NSWCMA), and determine regularisation factors that will optimise speed. We also show that the NSWCMA can outperform the minimum mean square error solution in terms of bit error ratio.
