Abstract: A method of dual transfer mode handover between a source base station (2) and a target base station (3) comprises preparing messages (6, 7) to a circuit switched CS network (4) and to a packet switched PS network (5) indicating a requirement for handover. An identifier (18 Fig. 2, not shown) is added to each message, wherein the identifier is the same for both networks. Each message is sent to its respective network and resources are allocated in each network. A signal (8, 9) is sent to the target base station (3) that a handover is requested and CS and PS requests are coordinated at the target base station, based on the identifier (18). An acknowledgment (10, 11) is sent to the respective networks and the source base station (2) coordinates handover commands (12, 13) from each network, based on the identifier, then sends a dual transfer mode handover command to the mobile terminal (1).

Abstract: A correction process for radio signals transmitted through a using channel after decision feedback comprises time unit processing of at least two trellis diagrams (UT,IT) where the condition of at least one diagram (UT) describes the use channel. Decision feedback sharing provides information from at least one disturbance channel.

Abstract: The invention relates to a device and a method for detecting bad or unreliable frames in a radio receiver, wherein the threshold values for the error rate or metric are adapted according to the type of transmission channel. A higher quality is required for slowly changing transmission channels than for rapidly changing transmission channels. The actual transmission channel type can be extrapolated from the percentage of data packets having metric zero.

Abstract: The inventive method is characterized in that a single standard-independent clock-pulse rate is generated in a signal processor or signal processing structure and a pulse frequency generator is disposed on the chip in a precise manner. The signal processing path comprises at least one controllable, asynchronous decimator for transposing the reception signal present in a single time frame to a respectively standard-specific time frame.

Abstract: The invention relates to the digital demodulation of a quadrature amplitude- or phase-modulated signal (xE(t)), whereby said signal is sampled with a sampling frequency fs and A/D converted, which has the following relationship, (1) with the carrier frequency f0, whereby lambda is a whole number greater than or equal to zero. The multiplications of the sampled and A/D converted quadrature amplitude- or phase-modulated signal usually necessary for demodulation, with the signal (2) and the signal (3) can be easily performed, whereby the individual sample values of the quadrature amplitude- or phase-modulated signal are multiplied by the value -1, 0 or 1.

Abstract: The filter has a phase shifter (1) receiving a received complex significant signal (x) phase of complex significant signal is shifted around a certain phase angle based on interference noise, where an out of phase signal (x`) generated. The shifter is connected upstream of a projection unit (2) that receives the signal (x`). The unit projects the signal (x`) on a direction in a complex level, where a projection signal is produced. Independent claims are also included for the following: (A) a pager (B) a method for elimination of interference noise e.g. same channel interference noise in received complex significant signal.
