THE IMPACT OF SIZE OF OFDM-SIGNAL RESOURCE BLOCK ON LTEAND McWILL NETWORKS PERFORMANCE

摘要

The analysis of the impact of size of resource block (RB) of the OFDM signal on the performance of 4G networks was performed. For the digital exchange was proposed the method and the performance indicator, which allows to consider the effect of the RB size on the data transmission speed and the probability of congestion (GoS). Established that the size of discrete portion of the resource 2RB, which is used for resource allocation in LTE, is too great. This can lead to the loss of the radio channel performance and to the growth of the GoS. In McWILL the size of discrete portion of the resource is set with accuracy up to 1/8RB. It is shown that in this case the loss of performance no occurs.
