Multicarrier systems are highly sensitive to the intercarrier interference (ICI) caused by a carrier frequency offset (CFO) at the receiver and to the intermodulation distortion (IMD) introduced by the nonlinear amplifier (NLA) at the transmitter. We analyze how these impairments degrade the bit-error rate (BER) of multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) downlink systems in frequency-selective Rayleigh fading channels.

Abstract
Multicarrier systems are highly sensitive to the intercarrier interference (ICI) caused by a carrier frequency offset (CFO) at the receiver and to the intermodulation distortion (IMD) introduced by the nonlinear amplifier (NLA) at the transmitter. We analyze how these impairments degrade the bit-error rate (BER) of multicarrier direct-sequence code-division multiple-access (MC-DS-CDMA) downlink systems in frequency-selective Rayleigh fading channels.File in questo prodotto:
