Performance Analysis Of Ufmc In Massive Mimo System Under Channel Uncertainty

Abstract

Multiple-Input Multiple-Output (MIMO) Is A Radio Antenna System That Uses Multiple Antennas At Both The Transmitter And Receiver To Improve The Radio Link's Quality, Throughput, And Capacity. MIMO Uses Techniques Known As Spatial Diversity And Spatial Multiplexing To Transmit Independent And Separately Encoded Data Signals, Known As "Streams", Reusing The Same Time Period And Frequency Resource. Massive MIMO Refers To The Use Of A High Number Of Antennas On A Base Station In Order To Serve Many Active Users In The Same Time Frequency Block. The Capacity Of Massive MIMO To Increase Throughput And Spectral Efficiency Has Made It A Crucial Technology For Emerging Wireless Standards. Orthogonal Frequency Division Multiplexing (OFDM) Have Been The Most Attractive One For The Development Of Wireless Communication System Like 4G In The Advantages Like Ease Of Implementation, Immunity To Interference, High Data Rate Etc. In This Thesis, We Provide The Analysis And Comparison Of The Candidate Waveforms, Filter Bank Multicarrier (FBMC) And Universal Filtered Multicarrier (UFMC). FBMC Introduces An Overhead In Overlapping Symbols In The Filter Bank In The Time Domain. Universal Filtered Multicarrier (UFMC) Inherits The Robustness Of FBMC And Simplicity Of OFDM. In This Thesis, Performance Comparison In Terms Of Spectral Efficiency, Power Spectral Density (PSD), Peak To Average Power Ratio (PAPR) And Bit Error Rate (BER) Presented. The Result Demonstrates The Benefits And Drawbacks Of Each Modulation Scheme. Furthermore, We Can See From The Simulation Results That UFMC Has A Lower BER Value At Low SNR Values, Indicating A High Receiver Sensitivity That Is Conducive To Better System Performance. Due To Long Filtering Length In FBMC It Is Insensitive To Multiuser Interference To Support Different Use Cases With In Same Bands. UFMC, Reveals To Be Most Promising Which Close To OFDM With Advantage Of Better Out-Of Band (OOB) Emission. Finally, In Order To Improve Spectral Efficiency, The UFMC Waveform Is Well Suited As A Modulation And Demodulation Technique For Massive Multiple-Input Multiple-Output (M-MIMO) Technology
