adjacent channel interference造句

• Research on first adjacent channel interference in fm iboc dab
  系统第一邻频道干扰研究
• Aci adjacent channel interference
  邻频干扰
• So , at the frequency 1920mhz , phs will be adjacent to wcdma uplink , there will be fairly strong adjacent channel interference between them , compared to phs and wcdma downlink , which could be neglected
  Phs系统将紧邻wcdma系统的上行频带,在1920mhz频点附近两系统将会对彼此产生比较强的邻频干扰,由于频带距离较远,可以忽略wcdma下行频带和phs之间的干扰。
• Since the envelope of modulated signal fluctuates , these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ) . so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci )
  但包络变化的调制信号经过非线性射频功放后会产生交调分量，因此必须采用线性化技术来减少由此产生的邻道干扰。
• For implement of wide band modulation , multi - carries and elimination of adjacent channel interference to satisfy ber requirement in wcdma system , which is most popular in 3g technology , the linearity requirement of the base station power amplifier becomes tighter
  以wcdma为代表的第三代移动通信技术,为实现宽带调制、多载波应用,同时减小邻信道干扰以满足通信系统的误码率要求,对基站发射机功放的线性指标要求苛刻。
