摘要： A radio apparatus according to a TDMA/TDD system uses its own transmitter (2) and receiver (3) so as to perform a loopback test for checking normality of the apparatus (1A) during a period of an unassigned slot. A loopback test signal is output from its own transmitter (2) during an unassigned transmitting slot and is received by its own receiver (3). The signal is temporarily stored in a memory (14) and is read during an unassigned receiving slot. The apparatus (1A) thus performs a loopback test. Since a loopback test can be performed by use of its own transmitter (2) and receiver (3) during an unassigned slot, a transmitting and receiving device (tester) specifically used for a loopback test is not required. Also, a loopback test can be carried out even while normal communications are being made.

摘要： In this demodulation method, a receive signal is demodulated estimating the fading distortion of data by detecting the fading distortion of unique word as pilot signal inserted into multiple sections of the receive signal. The method has the steps of: comparing a unique word in the multiple sections of receive signal and a known unique word and thereby detecting the fading distortion of unique word in the multiple sections; calculating a spline interpolation curve based on the fading distortion of unique word in the multiple sections; estimating the fading distortion of data in the receive signal from the spline interpolation curve; and demodulating the data in the receive signal based on the fading distortion of the data.

摘要： Die Erfindung betrifft ein Verfahren und eine Schaltungsanordnung zur Erkennung und Reduzierung von Multipathstörungen in einem Rundfunksignal. Bei diesem Verfahren wird ein Eingangssignal, welches mit Multipathstörungen behaftet ist, einem Spitzenwertgleichrichtereinheit zugeführt. Über eine Komparatoreinheit werden im Eingangssignal vorhandene Impulse, welche typischerweise bei Multipathstörungen auftreten, erkannt und die Komparatoreinheit triggert auf diese Störungen. Das hierdurch entstehnde Trigger-Signal wird entweder über jeweils mindestens ein Zeitkonstantenglied geführt und/oder zur Signalisierung an einen Mikrocomputer oder weitere Baugruppen geleitet. Das entstehende Signal wird zur Ansteuerung von verschiedenen Funktionen verwendet.

摘要： In a method and a device for generation of path profiles for use in radio wave propagation planning, several path profiles, adjacent to a generated first, primary path (501) are generated (503). Obstacles detected in the adjacent path profiles are then transformed and translated (505) onto the primary path profile, whereby a resulting path profile taking into account both obstacles present in the primary path profile and obstacles close to it. The method and the device are particularly useful in urban and suburban areas where obstacles tend to be of a discrete nature, and can be used for many types of applications such as point-to-point, point-to-multipoint and area coverage applications.

摘要： The invention relates to a device for looping a radio-frequency test signal transmitted by a transmitter section in a full duplex type transceiver to a receiver section for testing the transceiver. The device of the invention comprises mixing means (23, 28) for converting a test signal from a transmitting frequency to a receiving frequency and switching means (312 to 314, 316 to 317) by means of which the test signal can be connected from the output of the mixing means (23, 28) to a device output (13) and therethrough to the receiver section through two alternative signal paths with different fixed attenuations and gains.
