| description | Long Term Evolution(LTE) is an access technique that is used in radio networks. LTE provides highdata bandwidth in transmitting data by providing flexibility against noise andinterference. Orthogonal Frequency Division Multiplexing (OFDM) technique usesthe FDM (Frequency Division Multiplexer) modulation technique to increase theamount of carried information over the wireless network. The OFDM signal istransmitted to the receiver at different frequencies which they are orthogonalto each other by dividing the bandwidth of a signal into smaller sub-carriers.Recently, the use of polar codes as a coding scheme in the new generation 5Gsystems has come to the communications markets. Polar codes as a channel codingscheme are a promising technique for the future because it is the first codesthat reach Shannon capacity limit. The cyclical prefix – OFDM (CP-OFDM), whichis used in 4G systems, performs well in many aspects, however, it has muchweakness that make the researches look for a new modulation technique to beused in 5G systems. Filtered–OFDM (F-OFDM) is considered one solution to theproblems appeared in CP–OFDM. In this paper, the differences between CP-OFDMand F-OFDM regarding advantages and disadvantages of each type are studied indetails. The comparison between the two modulations waveforms are done bystudying their Error Vector Magnitude (EVM) that deals with measuring theaccuracy of the received signals. Furthermore, the comparison between the twomodulations waveforms with polar codes in the USRP B210 radio are applied tomake our work more practical. |
