Two-way radio equipment uses a variety of technical means in terms of anti-interference capabilities to ensure that it can operate stably and reliably in complex environments. The following are some of the main technical means:
First of all, spread spectrum technology is an important anti-interference method. Through spread spectrum, the signal is hidden in the noise, forming a wide-band pseudo-noise communication, thereby reducing the power density of interference or the probability of collision. This technology has strong anti-interference ability against narrowband interference and effectively improves the communication quality of Two-way radio equipment in interference environments.
Secondly, fast frequency hopping technology is also an important means to enhance anti-interference capabilities. This technology is particularly suitable for medium and low-speed frequency hopping communication systems that are susceptible to tracking interference. By quickly changing the communication frequency, it can effectively avoid the continuous impact of interference signals and ensure the continuity and stability of communication.
In addition, multiple-input multiple-output (MIMO) technology is also a new technology that has emerged in the field of wireless transmission in recent years. It uses multiple transmitting antennas to transmit signals at the transmitting end, and multiple receiving antennas at the receiving end to receive signals. This technology enables a wide range of data rate changes by providing large channel capacity, thereby improving the anti-interference performance of Two-way radio equipment in complex environments.
In addition, virtual smart antenna technology is also an effective anti-interference method. It utilizes the interaction between antennas or similar other communication devices in the same geographical area to achieve functions similar to smart antennas, thereby improving the interference ratio and anti-interference performance of the antenna signal receiving end.
In addition, software radio technology is also an important method to improve the anti-interference capability of Two-way radio equipment. Modular and standardized hardware units are connected in the form of a bus or network to form a basic platform, which can realize various wireless communication functions through network loading. The flexibility of this technology enables devices to adjust communication parameters and strategies according to different interference environments, thereby improving anti-interference capabilities.
To sum up, Two-way radio equipment uses a variety of technical means in terms of anti-interference capabilities. These technologies complement each other and work together to improve the communication quality and stability of the equipment in complex environments.
