Bluetooth: Channel Coding Considerations

Overview It has been found that several papers that address the performance of Bluetooth (BT) over a fading channel implicitly assume a perfectly interleaved channel and neglect the bursty nature of a fading channel. The goal of this paper is to analyze the effects of this incorrect assumption on BT's performance over a frequency-flat Rayleigh block fading channel. This paper shows that neglecting the bursty nature of the channel leads to overly pessimistic conclusions about the performance of Bluetooth in the low SNR region and, thus, that many reported results on the coexistence of Bluetooth and 802.11 are overly-pessimistic. The paper also concludes that the coding strategy used in Bluetooth has little or no effectiveness on a frequency-flat Rayleigh block fading channel.
