Embodiment Construction

[0062] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0063] As briefly explained in the previous background technology section, since the slave device does not know the frequency hopping sequence adopted by the master device, in order to perform synchronous access with the master device, the slave device first needs to receive the broadcast beacon sent by the master device, The broadcast beacon carries general information common to all slave devices in the wireless communication system, including master device address, frequency hopping sequence and so on. After receiving the broadcast beacon, the slave device can know the frequency hopping sequence adopted by the master device and synchronize with it.

[0064] and figure 1 The synchronous access method for frequency hopping wireless communication shown in the prior art is different. In t...

Abstract

The invention provides a synchronous access method carried out between first communication equipment and second communication equipment in frequency hopping wireless communication, related communication equipment and a related communication system. The first communication equipment adopts N frequency hopping channels to carry out frequency hopping in a predetermined frequency hopping sequence and at a predetermined frequency hopping time interval. The method comprises the following steps: the first communication equipment transmits a broadcast beacon on the N frequency hopping channels with M times of the predetermined frequency hopping time interval as a period, wherein the broadcast beacon carries general information including synchronization information, and M and N are natural numbers and are relatively prime; the second communication equipment receives the broadcast beacon on any frequency hopping channel among the N frequency hopping channels to obtain the synchronization information; and the second communication equipment and the first communication equipment carry out information interaction on to be accessed. By the adoption of the flexible, simple and easy-to-implement synchronous access scheme, efficient use of bandwidth and good anti-interference performance can be achieved, and fast and reliable synchronization can be carried out at very low power.

Description

technical field [0001] The present invention relates to frequency hopping wireless communication technology, in particular to a synchronous access method in frequency hopping wireless communication, communication equipment such as a master device and a slave device, and a frequency hopping wireless communication system including the master device and the slave device. Background technique [0002] Frequency hopping is a technique used to achieve reliable wireless communication in environments exhibiting frequency selective signal fading or unknown narrowband interference from other devices. In addition to being used in communication standards such as Bluetooth, frequency hopping has also been used in many proprietary wireless solutions, for example, to send wireless audio streams to hearing aids. [0003] In applications such as Body Area Networks, wireless sensor networks, etc., power consumption is an important design consideration. Especially for systems based on low-cos...
