Utilizing An Adaptive Beamformer For Improved Communications

Utilizing An Adaptive Beamformer For Improved Communications

Clear communications are important for individuals and companies in the effective and efficient conduct of their affairs. Clear voice communications simply saves time and money by avoiding misunderstandings and unnecessary calls. This has special significance for companies that depend on voice and telecommunications for conducting business.

When selecting a communications system for your business or personal use it is important to understand your application requirements and what technologies are available to address those needs. Application developers care about the underlying technology being used; users care about the end results.

An adaptive beamformer is particularly useful in video conferencing, multimedia systems, ultrasonic imaging, and wireless systems where it is used to enhance the signal of interest.  Adaptive beamforming is a technology that is finding increased use in mobile systems to improve signal quality and reduce noise.

In wireless communications, an adaptive beamformer steers the main beam in the desired direction to improve signal quality and increase reliability of the communications link. This provides an increase in range as well as throughput. In mobile systems it means fewer dead zones and dropped calls.

In voice systems, an adaptive beamformer steers the main beam in the direction of the speaker of interest to better capture the desired speech while positioning the null to ignore strong noise sources and other speech sources. People do this automatically when listening to a conversation in a noisy room while filtering out background chatter and other noise.

In speech enhancement, adaptive beamforming works in combination with echo cancellation and noise reduction to significantly improve the quality and intelligibilty of speech. Beamforming is used to enhance the signal of interest captured by the microphone whereas echo cancellation and noise reduction filter and remove echoes and residual noise from the captured signal.
