In this chapter we examine the effects of nonlinear distortions on OFDM waveforms caused by the radio frequency (RF) subsystems. Earlier chapters focused on the baseband signal representation. But the true test of the practicality of the system design is measured by the performance of the bandpass signal under impairments caused by the RF subsystems. In this chapter, we will see that as robust as OFDM systems are to some synchronization errors, they ...
