Another Major Breakthrough in VCO Technology

Z-Communications Inc.
No Comments
Modern digital communication systems using complex modulations such as Orthogonal Frequency Division Multiplexing (OFDM) or Quadrature Amplitude Modulation (QAM) require controlling bit error rate (BER) in order to achieve a given signal-to-noise ratio (SNR). The achievable BER is a function of many system parameters. Most important among them is...
