摘要： A transmitter clips a transmission signal before transmis- sion in order to reduce the strength of at least one peak of the transmission signal exceeding a predetermined threshold. The transmitter comprises a clipper comprises a minimizer (400), a filter (402) and an adder (404). The minimizer (400) minimizes of a cost function with respect to an optimisation signal, the cost function having weighted terms as a function of the optimisation signal, the terms relating to an effective modulation distortion and an effective overshoot exceeding the predetermined threshold. The filter (402) forms a clipping signal by filtering the optimisation signal formed as a result of the minimization according to the spectrum emission mask requirements of the radio system. The adder (404) subtracts the clipping signal from the transmission signal.

摘要： An interference estimation and suppression procedure is provided. A radio channel impulse response and interference parameters are estimated iteratively from a received training sequence by utilizing in each iteration of the radio channel impulse response estimation (204) the latest estimate of interference parameters and in each iteration of the interference parameter estimation (206) the latest estimate of the radio channel impulse response. After the iterative estimation procedures are completed, a received data sequence is filtered with a filter (208) having coefficients obtained on the basis of the final estimate of the interference parameters. Additionally, the received data sequence is equalized with an equalizer (210) having coefficients calculated on the basis of the final estimate of the radio channel impulse response.

摘要： The specification and drawings present a new method, system, apparatus and software product for a timeslot (TSL) reuse typically combined with a frequency reuse for a service based interference control in communication systems. TSL reuse method can be applied to a service with a wider spectrum or a higher symbol rate than for a normal channel bandwidth of a communication system to provide the way for controlling interference. The TSL reuse method can enable interference control for synchronized and unsynchronized networks in uplink (UL) or downlink (DL).

摘要： The specification and drawings present a new method, system, apparatus and software product for variable filtering of a mobile station (MS) for supporting uplink communications using available capabilities of a network element in wireless communication systems (e.g., evolved GERAN). The MS may have at least two different pulse shaping filter capabilities providing at least two different bandwidths: one narrower being suitable for legacy transceivers and another wider and thus optimal for variable symbol rate from performance point of view. A BSS (base station subsystem) may then request to use one of those filter capabilities according to BSS available resources
