He has made significant contributions to the field of wireless communication, holding 2 patents that enhance the quality and efficiency of mobile phone calls. His work is particularly relevant in today's fast-paced digital world, where communication technology continues to evolve.
Latest Patents
One of his latest patents is titled "Mobile to mobile digital wireless connection having enhanced voice quality." This invention aims to improve the subjective voice quality of mobile-to-mobile phone calls that utilize tandem vocoder processing. By modifying the spectrum of the voice signal before it is processed by the second vocoder, the invention compensates for digital distortion generated by the second vocoder. An adaptive filter can be employed to modify the spectrum of the voice signal, ensuring that the voice quality of a call from one mobile phone to another is comparable to that of a call from a mobile phone to a desk phone.
Another significant patent is "Mobile-to-mobile DTMF signaling in tandem free operation." This wireless communication method allows a user at one end to send dual-tone multiple frequency characters from one wireless unit to another while remaining in tandem free operation mode. By avoiding the transition to tandem operation mode during dual-tone multiple frequency signaling, the invention eliminates delays and distortions associated with CODECs used in tandem operation mode. This advancement ensures that bursts of dual-tone multiple frequency characters are transmitted without interruption.
