Performance Evaluation of Differential Modulation in LTE - Downlink
نویسندگان
چکیده
This paper evaluates the performance of differential modulation applied to the 3GPP UMTS Long Term Evolution downlink. With differential modulation, reference symbols for channel estimation are no longer necessary, thus increasing the potential maximum spectral efficiency. We present two basic modulation schemes and compare their performance to the coherent detection employed in Long Term Evolution downlink transmissions. The focus specifically lies on single input single output transmissions in single user scenarios.

Differential Modulation in LTE-Downlink
This diploma thesis evaluates the performance of differential modulation applied to the 3GPP Long Term Evolution downlink. The focus specifically lies on single input single output transmissions with only one user. The Long Term Evolution downlink is based on channel estimation. The reference symbols, required for channel estimation cannot be used to transmit data, which reduces the spectral ef...
متن کاملModeling and Performances Evaluation of HARQ Technique for MIMO Transmission in Downlink LTE Cellular Networks
Long Term Evolution (LTE) is designed for deployment in a variety of spectrum allocation ranging from 1.4 MHz to 20 MHz. The peak data rate envisaged for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. Unfortunately, different constraints have a strong influence on system performance such as the velocity of user equipment and effect of multipath channel. To achieve data rate compliance w...
متن کاملPerformance Evaluation Of Downlink LTE-Advanced CELL By MOSEL-2 Language
LTE or the Long Term Evolution is the biggest jump on the evolution path from 3G towards 4G, whereby data rates are 10x those of 3G using an all packet network. LTE-advanced is a 4G recognized mobile technology satisfying the IMT-Advanced of the ITU, which will provide peak data rates in the order of 1 Gbps on the downlink and 500 Mbps on the uplink. In this work, performance evaluation of one ...
