متن کاملPerformance Analysis of SC-FDMA and OFDMA in the Presence of Receiver Phase Noise
In this paper we study the effect of receiver phase noise on single carrier frequency division multiple access (SC-FDMA) and orthogonal frequency division multiple access (OFDMA). We show that in both SCFDMA and OFDMA, common phase error rotates all the symbols by a certain angle and that the higher order frequency components of phase noise result in inter-carrier interference, or ICI. We then ...
متن کاملPerformance Analysis of Sc-FDMA and OFDMA in LTE Frame Structure
Long Term Evolution (LTE) is consents pliable spectrum distribution which renders enriched wireless data services to users at lower latency and multi-megabit throughput. LTE uses Orthogonal Frequency Division Multiple Access (OFDMA) and Single Carrier Frequency Division Multiple Access (Sc-FDMA) for downlink and Uplink transmission where OFDMA has been acquired in LTE for downlink transmission ...
متن کاملAn Analysis of Ofdma, Precoded Ofdma and Sc-fdma for the Uplink in Cellular Systems
Orthogonal Frequency Division Multiple Access (OFDMA) appears today as a strong candidate in on-going standardization. Despite its attractive features, it has several drawbacks when employed in the uplink: The high peak-to-average power ratio (PAPR) inherited from Orthogonal Frequency Division Multiplexing (OFDM) and the inherent frequency diversity loss. The loss of frequency diversity can be ...
متن کاملAnalyzing the effect of Modulation order and FFT size on PAPR performance of SC-FDMA and OFDMA system
AbstractPeak to Average power ratio is the problem being faced in multicarrier system, for Long term evolution(LTE) research is being done for a kind of system that is having lesser PAPR. Single carrier Frequency division multiple access (SC-FDMA) and Orthogonal frequency division multiple access (OFDMA) are major part of LTE. OFDMA was well utilized for achieving high spectral efficiency in co...
