摘要： A base station and a method of configuring a base station are provided in a cellular telecommunication system, wherein the base station comprises an electrically tunable duplex filter with a tuning range covering at least two parallel sub-bands used in the telecommunication system. The electrically tunable duplex filter is tunable on site to a sub-band allocated to the base station, thus enabling an increased flexibility in selecting a fixed frequency band to be used in the lower frequency stages in the transceiver and the base band parts of the base station.

摘要： Signal instances are detected from within a long period of a received radiofrequency RF signal envelope, grouped according to signal level, and periodicities are determined among the grouped signal instances. Periodicity of one of the groups is matched to a known periodicity, and a frequency domain is estimated at a time instance derived from the matched periodicity. If an expected frequency pattern is found that occupies the derived time instance in the estimated frequency domain, then a receiver is synchronized to a candidate signal that lies within the frequency pattern. Then content of the candidate signal is decoded and that content is used to access a cognitive radio system (e.g., register to the system, start the normal operation in the network such as spectrum detection and/or transmission in a traffic channel, etc.).

摘要： A method for operating a receiver and a device are provided. The device comprises a first and a second antenna, a receiver operationally coupled to the first antenna and a transceiver operationally coupled to the second antenna. The receiver receives information in bursts on a first band of radio frequencies. A controller of the device measures signal strength of the information received with the receiver, compares the measured signal strength to a reference value and enables operation of the transceiver if the measured signal strength is above the reference value, and limits operation of the transceiver during reception of the bursts if the measured signal strength is below the reference value.

摘要： A method, terminal, and computer program are disclosed to reduce radio interference in a wireless communications device having a combination of a wireless telephone unit, such as a GSM cellular phone, and a short range wireless communications unit, such as a WLAN communications unit or a Bluetooth communications unit. An interference avoidance subsystem in the wireless communications device is connected between the GSM frequency hopping logic and the Bluetooth frequency hopping logic. Bluetooth frequency hopping information and time domain operation information are input from the Bluetooth frequency hopping logic to the interference avoidance subsystem. GSM frequency hopping information and time domain operation information are input from the GSM frequency hopping logic to the interference avoidance subsystem. The interference avoidance subsystem then uses this input data to calculate the interference probability between co-existing Bluetooth received signals and GSM transmitted signals. The interference avoidance subsystem then compares the calculated interference probability with the required Bluetooth packet error rate limit for the current application. If the interference probability exceeds the required Bluetooth packet error rate limit, the interference avoidance subsystem sends a signal to the Bluetooth frequency hopping logic to change the Bluetooth frequencies.
