Problems solved by technology

In this case, when the total power of transmission is not increased, the performance improvement of the system does not really achieve the best performance, and there will be a waste of output power in the average distribution, because the signals transmitted in different channels The quality is different, and it is very vulnerable to external interference, which will cause a serious decline in system performance

Embodiment Construction

[0022] Hereinafter, the present invention will be further described in detail with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0023] Such as figure 1 Shown is a schematic diagram of the structure of the multi-output Zigbee transmitting device of the present invention. The Zigbee transmitting device includes a data acquisition module for collecting data, a first data processing module for baseband data processing, and a signal A demultiplexer for decomposing into multiple signals, a second data processing module for channel data processing, and a parallel-to-serial converter for converting parallel data into serial data. The Zigbee transmitting device also includes a signal-to-noise prediction channel A ratio channel estimation module and a power allocation module that performs power allocation based on the channel estimation module predicting the signal-to-noise ratio of each channel. In the present invention,...

Abstract

The invention relates to a multiple output Zigbee launcher which comprises a data acquisition module, a first data processing module, a multipath resolver, a second data processing module, a serializer, a channel estimation module and a power distribution module, wherein the data acquisition module, the first data processing module, the multipath resolver and the second data processing module are sequentially connected; and an output end of the channel estimation module is connected into the power distribution module, and an output end of the power distribution module is connected into the second data processing module. According to the multiple output Zigbee launcher, a multiple output mode is adopted, simultaneous transmission in different channels can be carried out, an optimal power distribution mode is adopted, and thus system performance maximization comprising the maximum transmission rate or the maximum sending signal covering is achieved; and at the same time, receiving sensitivity, capacity of resisting disturbance and sending signal resource optimization of a short-haul communication equipment system can also be improved.

Description

Technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a multi-output Zigbee transmitting device. Background technique [0002] Zigbee (short-range, low-power wireless communication technology) is an emerging short-range, low-complexity, low-power, low-data transmission rate, and low-cost wireless network technology. It is a kind of wireless marking technology and The technical proposal between Bluetooth is mainly used for short-range wireless connection. It is based on the 802.15.4 standard to coordinate and communicate among thousands of tiny sensors. These sensors require very little energy to transfer data from one sensor to another via radio waves in a relay manner, so their communication efficiency is very high. [0003] The existing Zigbee technology adopts a single output mode or a balanced power distribution method for multiple outputs, and then uses a radio frequency module and amplifier for signa...
