双语例句
- LEO satellite communication system has the properties of larger power dynamic range, larger and faster changed doppler frequency shift and rapid fluctuation compared to ordinary communication system.
相对于一般的通信系统而言，低轨卫星通信系统具有信号动态范围大，多普勒频移大且变化速度快，信道起伏剧烈等特点。 - In the FM-QCSK ( Frequency Modulated Quadrature Chaos Shift Keying) communication system, frequency modulation of the continuous-time chaotic signal makes it possible to generate an inherent wideband signal with constant energy per bit.
在调频-四相混沌键控（FM-QCSK）混沌数字通信系统中，对时域连续混沌信号进行频率调制，使单位码元具有近似相等的比特能量； - Underwater acoustic channel experiences severe Multi-path extension, high ambient noise, limited bandwidth, large transmission and propagation delay, fluctuation effect and great doppler frequency shift. These features greatly reduce the reliability and effectiveness of underwater acoustic communication system.
水声信道具有多径扩展、高环境噪声、带宽受限、传输时延大、起伏效应和多普勒频移大等特点，这极大地制约了水声通信系统的可靠性和有效性。 - Orthogonal frequency division multiplexing ( OFDM) is a promising technique which can be thought as a hybrid of multicarrier modulation ( MCM) and frequency shift keying ( FSK) modulation and it is the main candidate technology for the new generation communication system.
正交频分复用（OFDM）是一项很有前途的技术，可以看成是多载波调制（MCM）和频移键控（FSK）调制的结合，是新一代无线通信传输的主要候选技术。
