摘要： A leading wave position detecting unit and method etc. is provided for detecting the position of the leading wave in a delay profile. Time spaces between sampled values (τ1–τ13) in the delay profile are measured. Among the measured time spaces, a maximum time space (τ8) is determined, and the position of its immediately following sampled value (sampled value (h)) is detected as a leading position. The initial peak of the sampled values after the leading position detected (position of sampled value (j)) is determined as a leading wave position.

摘要： A leading wave position detecting unit and method etc. is provided for detecting the position of the leading wave in a delay profile. Time spaces between sampled values (τ1-τ1 3) in the delay profile are measured. Among the measured time spaces, a maximum time space (τ8) is determined, and the position of its immediately following sampled value (sampled value (h)) is detected as a leading position. The initial peak of the sampled values after the leading position detected (position of sampled value (j)) is determined as a leading wave position.

摘要： The system for measuring the spillover signal from a transmitter to a receiver in a same frequency repeater or a booster has a frequency conversion device which slightly offsets the transmission frequency from the reception frequency, and a signal detector which measures the offset frequency component in the reception signal. The offset frequency is around 100 Hz, which is higher than the fading frequency, and low enough not to affect the operation of receivers. The measured spillover level is used to control the gain of the repeater, and/or to cancel the spillover signal, so that the repeater has the maximum gain without suffering from oscillation.

摘要： A re-use partition of cells in a mobile communication system has an outer cell (30) and an inner cell (20) which is provided in the outer cell (30). An interval of cells using the same channel or the same frequency in the inner cells is shorter than an interval in the outer cells, which is the nature of a re-use partition. Communication between a base station and a mobile station is carried out by using a channel having a higher received level of an outer cell channel or an inner cell channel. A base station has a first beam tilt antenna having tilt angle (.THETA..sub.out) for an outer cell (30), and a second beam tilt antenna having tilt angle (.THETA..sub.in) so that .THETA..sub.in is larger than .THETA..sub.out. A speech channel and a control channel are provided for each of the first antenna and the second antenna.

摘要： A mobile communication system is provided in which a base station commands a mobile station (or field monitor) to measure the field strength for a specific channel. The mobile station reports the measured results to the base station. The measured results are used in conjunction with base station identification codes to obtain a single representative value which is used to determine what channels can be selected and used by the system. This enables an existing cellular system to be utilized as a first mobile communication system, and makes it possible to construct a second mobile communication system in the same area as the service area of the first system.
