Comparison between FDD and TDD frame structure in SC-FDMA

Long Term Evolution (LTE) is the largest wireless communication technology which renders substantially increased data rates to gain higher efficiency in multimedia system. LTE provides flexibility of using existing and new frequency band as well as reduced cost per bit, increased services provisioning, lower response time and wider spectrum. To conciliate all types of spectrum resources Frequency Division Duplex (FDD) and Time Division Duplex (TDD) duplexing schemes are used in LTE to share the same underlying framework. This paper is an overview of comparison between FDD and TDD based on Peak-to-average power ratio (PAPR) analysis in Single-carrier frequency-division multiple access (SC-FDMA). The error performance is simulated based on Signal-to-Noise ratio (SNR) Vs. Bit Error Rate (BER) for two types of multipath channel i.e. ITU Pedestrian A channel and ITU Vehicular A channel and also Additive White Gaussian Noise (AWGN) channel is used.
