SWITCHING OF APPROPRIATE TRANSMISSION MODES IN LTE
Long Term Evolution (LTE) is an emerging 4G wireless access technology.It is showing a lot of promise in field trials and gaining acceptance among the major wireless vendors.The Long Term Evolution (LTE) standard for mobile broadband employs this MIM0 technique in its transmission modes which were defined in release 8.The advantage of using MIM0 is the improved performance in terms of coverage, spectral efficiency, reduced power consumption and peak throughput in LTE downlink, PDSCH channel can use several MIM0 techniques which includes transmit diversity, spatial multiplexing and beamforming.The antenna configuration in transmitting and receiving side may be 2x2, 2x4 or 4x4.However the performance of transmission modes varies with the variation of multipath channel, UE speed and UE location within a cell.So, it is necessary to analyze their performance by considering the above facts.In this paper, the throughput conditions are investigated by changing the UE speed and also changing multipath channel in order to find out which transmission mode is best for which condition.
