摘要/Abstract

摘要： 导出了加性高斯白噪声和Rayleigh衰落信道上非均匀16-DAPSK错误概率的简单闭合表达式.对于多媒体通信和组播传输而言,非均匀16-DAPSK是有用的.给出了带有删除卷积编码的非均匀16-DAPSK调制的性能.结果表明卷积编码可与非均匀16-DAPSK调制用于在无线电广播系统中传输附加消息,而对于基本消息几乎没有损伤.

Abstract: Simple closed-form expressions for the probability of error for nonuniform 16-differential amplitude phase-shift-key (DAPSK) signaling over an additive white Gaussian noise (AWGN) and Rayleigh fading channels are presented. The performance of nonuniform 16-DAPSK with punctured convolutional coding is presented. The results show that the coding can be used with nonuniform 16-DAPSK modulation to transmit additional message in radio broadcasting systems with little degradation to the basic message.

Key words: multimedia transmission, nonuniform DAPSK, punctured convolutional coding, additive white Gaussian noise, Rayleigh fading channel
