With the same code length and error rate, the number of online users can be up to twice of that in binary phase shift keying ( BPSK ) CDMA system in the electronic domain. 在同码长、同误码率情况下,系统在线用户数可达电域中二进制相移键控(BPSK)(BPSK)码分多址系统的两倍。
The design was implemented with binary phase shift keying ( BPSK ). 设计的系统采用二相键控(BPSK)方式实现。
Thirdly, we quantify the power penalty caused by the PMD in optical subcarrier multiplexing ( OSCM ) system with amplitude shift keying ( ASK ) and binary phase shift keying ( BPSK ). 第三,对采用不同调制格式(包括幅移键控和二进制相移键控(BPSK))的光副载波复用(OSCM)系统中,PMD引起的功率代价进行了量化。
The Binary phase shift keying ( BPSK ) and Mary amplitude shift keying ( MASK ) are widely used in radar systems, their elliptic covariance do not equal zero, are noncircular signals. 二进制相移键控(BPSK)(BPSK)和幅度调制(MASK)等信号是雷达系统中常用的信号,这种调制信号的椭圆协方差矩阵不为零,被称为非圆信号。
To overcome the problem of " inverse π" of 2 PSK ( Binary Phase shift keying ), a new kind of non coherent demodulation for 2 PSK was proposed, and the principle and noise resistance of the system was analyzed. 从克服二进制移相键控(2PSK)的倒π现象出发,提出一种2PSK非相干解调法,并对其解调原理和抗噪声性能进行了详细的分析介绍。
