10 Methods of Signals Processing in Radio Access Networks

Abstract

This article considers optimum stochastic methods of radio signal processing, including parameter assessment tasks and management of parameters of receiving and transmitting devices. Such tasks are formed by state variable methods using Kalman-Bucy optimum recursive procedures. It’s recommended to solve the management problems basing on the division theorem. The article gives analysis of steadiness and efficiency of state and management assessment procedures in steady-state and unsteady-state conditions. It gives recommendations regarding the choice of parameters and efficiency of processing devices taking into account statistics of signals and constraints attributable to certain telecommunication technologies. It analyzes a proposal, within which recursive procedures are used efficiently. The main tasks are united on Multiple-input/Multiple-output (MIMO) principle and are aimed at solving the access problems in mobile communication networks, Wi-Fi and Wi-Max systems, etc. Such tasks include: space-time encoding, multipath effect reduction, radio link power improvement, interference effect reduction, adaptation to channel parameter changes and current signal interference situation, possible repeated use of frequencies.
