A multi-output zigbee transmitter

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, relates to a multi-output Zigbee transmitting device. Background technique [0002] Zigbee (short-range, low-power wireless communication technology) is an emerging wireless network technology with short-distance, low complexity, low power consumption, low data transmission rate, and low cost. A technical proposal between Bluetooth, which is mainly used for short-range wireless connections. It coordinates and communicates among thousands of tiny sensors based on the 802.15.4 standard. These sensors require very little power to relay data from one sensor to another via radio waves, so they communicate very efficiently. [0003] The existing Zigbee technology uses a single-channel output mode or a balanced power distribution method for multiple outputs, and then transmits signals through radio frequency modules and amplifiers and consists of simple co...

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
