Benefits of technology

This technology reduces errors caused when transmitting signals between devices over wireless networks without requiring complex equipment like an equalizer module. It uses two parts - one on top of another called a signal strength detector (SQ) and a groomer unit located near each other's receiver end. When there are no stronger signals being sent from device A towards B, it sends this weakened version back into their original form along with some noise. To prevent interference during communication, they also adjust the transmission based upon these reduced levels detected by Sqnetering Units placed close enough together.

Problems solved by technology

This patented technology proposes a solution called a Compensating Module that helps reduce interference caused by signals stronger than usual while still maintain good quality reception even at lower levels of intensity level. It involves measuring how much more powerful one's own receive signal has been captured compared against what they have previously stored beforehand. By comparing these measurements over time, adjustments could be made based upon factors like distance travelled through space being covered within 3 meters.

Abstract

The invention discloses an interphone and a circuit for reducing a bit error rate of the interphone. The circuit for reducing the bit error rate comprises a signal strength detecting unit and a dispersing unit. The signal strength detecting unit is used for detecting the signal strength of input signals and generating strength signals, and received signals are acquired by a receiving port of the interphone to obtain the input signals; the dispersing unit is used for dispersing partial power of the received signals to a grounding end according to the strength signals, and the received signals are outputted by an amplifier of the interphone. The interphone and the circuit for reducing the bit error rate have the advantages that the bit error rate can be reduced when the received strength signals are received, and the interphone and the circuit are simple and are high in response speed.
