Software Model of a 5G Data Transmission System with Increased Spectral Efficiency

At present, an actual task is to increase the throughput of cellular communication systems; in conditions of a limited frequency resource, the only solution is to increase the spectral efficiency of the signals used for data transmission. The signals used in the 5G system are based on orthogonal frequency division multiplexing, which for channels with memory requires the use of a cyclic prefix that reduces the spectral efficiency by up to 7% depending on the mode of transmission. In this work, we have developed a model of a data transmission system based on a filterbank multicarrier, which made it possible to exclude the cyclic prefix, and the obtained simulation results showed noise immunity results similar to the existing solution.
