SENSITIVITY OF OFDM/CDMA TO CARRIER PHASE JITTER
It is known that multi-carrier systems are more sensitive to carrier phase jitter than single carrier systems [7]. This carrier phase jitter is generated by the phase locked loop (PLL) which converts the received IF signal to the base-band signal. In the OFDM/CDMA system, the carrier phase jitter occurring in the PLL systems gives ... Return Doc
