    摘要: In a method for qualification of a frequency channel in a wire-free communication system, data is transmitted on different frequency channels by means of an adaptive frequency hopping method. The transmission and reception are carried out in time slots using a time slot method which is based on the radio standard. In order to qualify the transmission quality of the frequency channels, data packet error rates and/or bit error rates and the field strength of the received data signal are measured, and the measured field strength is compared with a threshold value field strength in order to make a selection decision.

    摘要: A packet-oriented mobile radio transmission system takes account of a packet utilization level that indicates how much of the maximum amount of payload information that can be transmitted is used for transmission. Such packet utilization level is a function of the packet type. A packet type that is suitable in the respective reception conditions is selected at the receiving end as a function of a variable that is characteristic of the integrity of the received data, and of the packet utilization level. At the transmission end, the packet type is switched as a function of the selection result.

    摘要: A method for calculating the power consumption of a mobile device, particularly of a mobile station of a mobile radio system, in an observation period Δt based on various possible system states sk in which the device can be in the period Δt. A value of a quantity Δk is determined system-state-dependently for the system states sk occurring in the period Δt. The power consumption in the period Δt is calculated in such a manner that the quantities Δk and state-dependent typical currents ik are taken into consideration.

    摘要: The document specifies a method for determining field strength which can be used in mobile radio systems, such as Bluetooth. The principle proposed involves alternate transmission and reception in the mobile radio system, with each timeslot comprising at least one time interval for transmitting/receiving a data block (RX, TX). The reception field strength (RSSI) is measured directly before (A, B) or directly after (C, D) transmission or reception of the data block (RX, TX). This allows the number of locking operations required in a PLL to be reduced and still allows adaptive channel adjustment to be performed, for example in a “frequency hopping method”, by measuring all channels without reducing the net data rate.

    摘要: The present invention relates generally to a converter circuit with a limiter to convert an analog reception signal into a value-discrete limiter signal. An evaluation circuit determines a zero crossing distance signal from the temporal distances between successive zero crossings of the limiter signal. A synthesis circuit calculates a digital processing signal whose zero crossings correspond to those of the limiter signal and whose pulse shape has a smaller spectral width than a rectangular pulse.
