| 摘 要： | 蓝牙2.0+EDR规范新增DH分组没有有效的纠错机制,其抗干扰能力差。通过在新规范中加入BCH编码和交织编码,以改善蓝牙的数据传输吞吐量及抗干扰能力。对于新增的数据分组,根据蓝牙标准协议,推导了相应的分组特性;建立了GE信道下数据传输速率与信道突发错误水平的关系模型;获得了在不同信道突发错误水平下的数据传输吞吐量。结果表明,在蓝牙2.0+EDR新规范中加入BCH编码和交织编码,在较高突发错误水平的信道中,其数据传输吞吐量提高了一倍以上,明显改善了数据传输的抗干扰能力。

| Abstract: | The new DHx packets are adopted in Bluetooth 2.0+EDR specification.Without any error correction coding mechanism,it has poor anti-interference ability in the burst errors channel.To enhance the data transmission throughput and anti-interference ability efficiently,a method by introducing new packets with BCH codes and interleaving to the Bluetooth 2.0+EDR specification is proposed.The packet properties of new packets are deduced based on the packet definition of Bluetooth specification.An analytical model o... |
