Embodiment Construction

[0039] The present invention is mainly applied to communication systems. The communication system mainly includes base station equipment, feeders and antennas. A base station equipment has at least one transmission channel. The carrier frequency of the signals transmitted on each transmission channel can be the same or different, the broadband can be the same or different, and the power Can be the same or different. The at least one transmission channel may share the same feeder, and different base station devices may also share the same feeder. The base station equipment is used to generate the original signal with a predetermined power. After the transmission channel is selected, it is transmitted to the antenna through the feeder. Due to the path loss, the signal received by the antenna has a path loss compared with the original signal, and the antenna radiates wireless to the coverage area. Signal. The path loss of the original signal transmitted from the base station equ...

Abstract

The invention discloses a path loss calculating and compensating device and a path loss calculating and compensating method. The method comprises the steps of: obtaining performance parameters of an original signal which is generated by a base station device and transmitted to an antenna through a transmission channel, and performance parameters of an antenna receiving signal after the original signal reaches the antenna; and calculating the path loss of the transmission channel according to the performance parameters of the original signal and the antenna receiving signal. According to the path loss calculating and compensating device and method, a practical, accurate and convenient path loss calculating scheme is provided without consuming a lot of manpower resources to measure the path loss and estimating the path loss according to cable indexes, and on the basis, loss compensation is further performed, thus ensuring stability of power, coverage range and network performance of the antenna radiation signal, and also allowing the maximal power of the antenna radiation signal to accord with the cell maximum transmission power configured at the background by a webmaster.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a calculation and compensation device and method for path loss. Background technique [0002] The existing communication system mainly includes three parts: base station equipment, feeder and antenna. The base station equipment generates signals with predetermined power, carrier frequency and bandwidth under the control of the network management background. After the transmission channel is selected, it is transmitted to the antenna through the feeder line. The coverage area radiates wireless signals. There is a path loss in the path where the signal is transmitted from the base station equipment to the antenna, which is called the path loss of the transmission channel. In fact, it mainly includes the transmission loss of the feeder. This loss directly affects the coverage and network performance of the wireless signal radiated from the antenna. [0003] Antennas are often ...
