Abstract: Abstract This paper presents a reconfigurable Fast Fourier Transform (FFT) hardware architecture for 3GPP LTE systems. In the main FFT computing process, a novel processing kernel engine is proposed to support four configuration types of…

Abstract: Commercial long-term evolution (LTE) systems adopt an access class barring (ACB) mechanism in the initial random access procedure with multiple preambles in order to accommodate bursty traffic arrivals of machine-type communications. In this paper, we…

Abstract: In this paper, the partial transmit sequence (PTS) technique is used to decrease the peak-to-average power ratio (PAPR) of the localized single-carrier frequency division multiple access (LFDMA) in the uplink of LTE systems. For a…
