摘要：
In this paper, a throughput improvement for wireless Bluetooth link by using adaptive packets is presented. Channel Quality Driven Data Rate (CQDDR) is employed to select the packet size by Received Signal Strength Indicator (RSSI) over Bluetooth network according to channel conditions. In this paper we improve the throughput over Bluetooth system in classic and Enhanced Data Rate (EDR) packets. Also, we study the adaptive Bluetooth packet format according to CQDDR decision, which determines when it can extend the payload (PL) of the transmitted packets. In addition, we proposed transmitting uncoded Access Code (AC) and the header (HD) as optional packets. Many of the proposed packet formats are studied in additive White Gaussian Noise (AWGN) and fading channels. Our simulation experiments reveal the capability of extension of the PL length by 8 bytes for classic BT and 16 bytes for EDR BT. Also, the experiments reveal ineffectiveness of error control schemes of AC and HD in the case of uncoded packets (DH1). That means that in good channel conditions, the redundant bits can be added to exceed the length of the PL.
