Abstract: The specification and drawings present a new method, system, apparatus and software product for carrier frequency shifting in mobile communication systems, e.g., for eliminating or reducing interference, e.g., for a communication between a mobile station and a network element. The communication between the mobile station and the network element may be performed within a GSM/EDGE radio access network. A signal (e.g., a DSR or MDSR carrier) and at least one further signal (e.g., a speech carrier) are identified, wherein bandwidths of the signal and of the at least one further signal overlap. Then, a frequency shift for said signal may be determined according to a predetermined criterion and a carrier frequency of the signal may be shifted by the determined frequency shift, e.g., for eliminating or reducing the interference.

Abstract: An indicator of a strength of a signal comprising a training sequence portion received in a radio propagation environment is provided. Samples are taken from the training sequence portion, an energy value of the samples over an estimated channel impulse response is computed and the indicator of the strength of the signal is estimated from the energy value.

Abstract: The specification and drawings present a new method, system, apparatus and software product for using a new modified dual symbol rate (MDSR) in an uplink direction in mobile communication systems. The communication between the mobile station and the network element may be performed within evolved GSM/EDGE radio access networks. The MDSR can be for example one and a half times a symbol rate of an uplink speech service, e.g., the current GSM/EDGE symbol rate (13/48 MHz) in the mobile communication system, thus the MDSR may be substantially 13/32 MHz or about 405 kHz. The uplink signal with the MDSR may be modulated, e.g., using a quadrature amplitude modulation (QAM), e.g., 16-QAM with 16 states and/or a quadrature phase-shift keying (QPSK, or ?/4-QPSK) modulation.
