摘要
对高速无线局域网IEEE802.11b基带特有的补码键控(complementarycodekeying,CCK)调制在高斯信道条件下的性能进行了分析.从补码的特性出发,根据CCK调制规则,采用相关解调,推导在加性白色高斯噪声信道条件下CCK调制的性能表达式.在COSSAP环境下按高速无线局域网标准构建链路进行仿真,由性能公式计算的结果和按标准进行的链路仿真结果相近,证明了导出的CCK调制性能公式是准确和实用的.
The performance of complementary code keying (CCK) modulation adopted in IEEE 802.11 b was analyzed under additive white Gaussian noise (AWGN) channel. The closed-form expressions for CCK modulation performance were derived from correlation demodulation according to the complementary code properties and CCK modulation regulation. The link consistent with standard IEEE 802.11 b was constructed over COSSAP platform. Comparisons between numerical and simulation results verified the accuracy and practical value of the derived closed-form expressions for CCK modulation performance.
