Two new Bluetooth receiver designs, the so-called modified limiter-discriminator detector with integrate and dump filtering (LDI) and noncoherent sequence detection (NSD), have recently been proposed in the literature. These receivers have been shown to improve the Bluetooth system performance in terms of physical-layer measures like bit-error rate (BER) and packet-error rate (PER) compared to the conventional LDI receiver. In this paper, we present a more comprehensive performance comparison for these receivers, which includes consideration of the spatial distribution of Bluetooth devices, channel propagation, data traffic, scheduling, automatic repeat request (ARQ), and baseband packet selection. The performance is measured in terms of practically relevant metrics such as end-to-end delay and throughput. Our numerical and simulation results verify that incorporating the new receivers into Bluetooth devices can considerably improve data-rate and quality-of-service performance compared to employing state-of-the-art LDI receivers.
