ABSTRACT

This chapter presents the performance analysis, in terms of Bit Error Rate (BER), for Orthogonal Frequency-Division Multiple Access (OFDMA) and Single Carrier Frequency-Division Multiple Access (SC-FDMA) transmissions over Rayleigh and Nakagami-m fading channels. It provides the reader with a brief description of those transmission schemes that were chosen for downlink (OFDMA) and uplink (SC-FDMA) transmission in the Long Term Evolution for the Universal Mobile Telecommunications System. The chapter also discusses the main features of the Nakagami-m fading channels and BER analysis technique. Concretely, it addresses the case in which zero-forcing frequency domain equalization is applied to compensate the effects of the channel on the received signal. The analysis is focused on the effects of equalization on the noise term before the decision stage.
