Abstract

In this paper the dual symbol rate (DSR) concept is proposed for GERAN networks. DSR doubles the modulation rate and user bit rate per radio time slot. Basic assumption is that the transmit signal of adjacent channels overlap in frequency domain. Interference rejection combining algorithms (IRC) are used to combat the introduced interference. Analysis of theoretical channel capacity suggests that data rates can be improved either by increasing the number of antennas or frequency bandwidth in the used radio links. Simulation results are given to demonstrate possible DSR deployment to the existing networks. Spectral efficiency, coverage and user bit rates are shown to be significantly improved
