Abstract

In this paper, we present a receiver design for Bluetooth transmission based on Laurent's decomposition of the Bluetooth transmit signal. The main features of this receiver are 1) its low complexity compared to alternative solutions; 2) its excellent performance close to the theoretical limit; and 3) its high robustness against frequency offsets, phase noise, and modulation index variations, which are characteristic for low-cost Bluetooth devices. In particular, we show that the devised noncoherent decision-feedback equalization receiver achieves a similar performance as a recently proposed two-state noncoherent sequence detector, while it is advantageous in terms of complexity. The new receiver design is therefore highly attractive for a practical implementation.
