【摘要】 在无线体域网极低信噪比环境下,引入循环谱检测技术可以很好的加以应对。但是在实际无线传输帧结构中,固定的帧结构会导致循环谱特性的损失,从而影响循环谱检测的性能。重点研究了在无线体域网中数据帧结构的设计,考察不同长度和样式的帧前缀对检测性能的影响。更多还原

【Abstract】 Cyclostationary detection can be reasonably introduced in Wireless Body Area Network(WBAN) environment in which ultra low signal SNR is necessary.However,the fixed frame structure in practical wireless transmission frame will cause the loss of the property,and therefore,affect the function of cyclostationarity.An exploration of the data frame design in WBAN is presented and the impact of length and pattern for different frame preambles are carefully considered and evaluated.更多还原
