The explosive growth of mobile communications, and the overly crowded and expensive spectrum have pushed both system engineers and operators to make their systems as spectrally efficient as possible in order to accommodate the increasing traffic dema

Re-farming of 900 MHz band into HSPA has been started and is likely to happen later with LTE. Typically operators have less than 10 MHz block of 900 MHz spectrum and therefore co-existence of two systems in that band is causing challenges. One of the

The further evolution of GSM/EDGE Radio Access Network (GERAN) is currently a subject to standardization in the Third Generation Partnership Project (3GPP). The objectives include significant improvements on user data rates, spectral efficiency and c

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. Int
