Abstract :
In asynchronous slow frequency hopping Bluetooth networks, packet collisions diminish the total link throughput. However, interference mitigation capability can reduce packet losses due to collisions. In this paper, an interference cancelling dual decision feedback (IC-DDF) Bluetooth receiver is proposed and its performance is evaluated for slow fading indoor channels. In addition to the bit error rate (BER) performance, the system level performance is evaluated by using the packet error rate (PER). To integrate the BER performance into PER performance, a new geometric interpretation of packet erasure rate using the received carrier to interference ratio (CIR) is introduced. Also, a generalized packet collision probability is derived to analyze total link throughput.
