Experimental and theoretical study of OTA throughput of 4G LTE wireless terminals for different system bandwidths and coherence bandwidths in Rich Isotropic Multipath

The 3rd Generation Partnership Project (3GPP) has provided successful reports and specifications for Long Term Evolution (LTE). The LTE standard is the latest communication technology standard today which is extensively adopted by the industry to satisfy the demands of their customers with high speed internet and low latency. The major differences between LTE and its predecessor telecommunication standards i.e. WCDMA and GSM are Orthogonal Frequency Division Multiplexing (OFDM), Multiple-Input Multiple-Output (MIMO), and scalable bandwidth which provide improved receiver sensitivity, higher throughput data-rates, and flexibility. The purpose of the present paper is to study measured throughput for different system bandwidths and see how well the OFDM model works for all these, and to investigate how the threshold level change with the system bandwidth.
