Problems solved by technology

[0017] 1. It is necessary to increase the cost of hardware to support the power boost process of combining two signals to increase power;
[0018] 2. There will be additional loss in the power amplifier combining process, which will reduce the output power after combining;
[0019] 3. The link through which the signal passes is the power amplifier input signal switching matrix, power amplifier 1, power amplifier 2, power amplifier input signal switching matrix and the connecting cables between these functional units. These links through which the signal passes have strict phase requirements for the signal, otherwise it cannot Achieving an effective power boost increases the power combining loss
But these strict phase requirements are difficult to achieve in practical design
[0020] To sum up, there is currently no reliable and economical technical solution for high transmit power requirements

Embodiment Construction

[0050] The core idea of ​​the present invention is to divide each code channel signal of the same carrier signal into at least two groups of grouping signals according to predetermined rules, and select one of the at least two groups of grouping signals contained in each code channel signal to form a group to be transmitted Signals, at least two groups of corresponding signals to be transmitted are obtained in total; the at least two groups of signals to be transmitted are respectively subjected to radio frequency conversion, power amplification and duplex processing, and then transmitted through the transmitting antennas independently set for each group of signals to be transmitted .

[0051]The reason why the above scheme can be used for processing is that the working principle of the base station transmitter of the CDMA system is as follows: the transmission signal of one carrier is combined by the signals of multiple code channels, and the multi-carrier transmission signal ...

Abstract

The invention relates to a method for improving the emission power and a relative system, wherein based on the emitter of CDMA system, it divides each code channel signal of same carrier wave into at least two paths, and select one path to form one group of emitted signals, to obtain relative at least two groups of emitted signals, and via the treatments of radio conversation, power amplify and receiving / sending duplex on said emitted signal, sending them via the independent emitting antenna. The invention is simple and reliable, with lower cost.

Description

technical field [0001] The present invention relates to a method and system for boosting power, in particular to a method and system for boosting transmission power applied in a CDMA system. Background technique [0002] In actual life, cellular mobile communication systems are used in various occasions, such as densely populated urban areas, relatively sparsely populated rural areas, and some rare areas covered by grasslands and sea levels, and various areas are different The mobile communication services required by different groups of people are different, some services are widely used and some services are only used on specific occasions. [0003] The above situation leads to a large requirement on the transmission power of the base station transmitter in some application scenarios. [0004] For example, the application scenarios that require a lot of transmission power are due to the low traffic in these areas, so it is hoped that the coverage of the base station will ...
