GSM Buzz (Cellphone/
Blackberry Interference) Restoration Audio Demo
What is GSM Buzz?
Cellular phone (GSM , TDMA, and CDMA) or Blackberry
PDA’s send out strong electromagnetic (EM) pulses during registration process.
These cellphone interference pulses are received by
audio amplifiers and line in circuits and causes noise known as GSM Buzz.
Using a Bayesian Statistical method, these noises can be detected and removed in real-time.
