User:BabakVosooghzadeh/Ultra Weak Signal Processing Foundation

The Ultra Weak Signal Processing Foundation was founded by Babak Vosooghzadeh in order to resolve the harsh requirements of future wireless systems which include the increase in transmission distance for existing personal wireless systems (Cellular Video phones, Sat phones, Wi-Fi, WIMAX, UWB,…), the increase in user capacity, the low power operation for eliminating the (health hazard) radio frequency power overload in dense wireless deployments, and the ability to perform co-channel signal source separation in extremely low power operation.

The Ultra Weak Signal Processing Foundation provides the technology, market analysis, and the guidelines for implementing the ultra weak signal recovery sub-modules in the communication receivers.

Cryogenic or cryo-cooler wireless receivers can handle the ultra weak signals in cellular or relay stations and portable wireless units. For the compact wireless hand sets, cryogenic receivers can not be deployed due to the space requirement for the cooling process. However, ultra weak signal processing can operate in ambient temperature conditions, and for cryogenic receivers, the signal processing provides improvement in signal detection.

ULTRA WEAK SIGNALS

The ultra weak signals are defined as desired communication signals that have receiver power levels below the noise floor. The receiver analog modules including the LNA(s) and the digital modules can not function properly, unless the desired signal power level is effectively boosted to levels above the noise floor. In the communication receiver, the ultra weak signal processing recovers the desired signal by employing preamplifier analog sub-module before the LNA(s) along with the associated digital processing sub-module. The Ultra Weak Signal Processing does not require extra bandwidth or transmission protocol modifications for its operation.

APPLICATIONS OF ULTRA WEAK SIGNAL PROCESSING

The ultra weak signal processing is required for the following reasons:

1- To detect wireless signals which are attenuated at levels below the noise floor due to low transmission power, long transmission distance, obstructions in indoor environments, etc.,

2- To increase the transmission distance for wireless networks that have been traditionally used for short distances without increasing the transmission power,

3-To allow for the deployment of massive wireless sensors & actuators and their networks at ambient temperature conditions for remote operation,

4-To increase the capacity for wireless service by operating in a low r.f. power environment and by eliminating the r.f. power overload,

5-To allow for the inclusion of signal source separation modules in the wireless sets,

6-To provide a market for massive communication services, and wireless modules that will be included in almost all of the electronic and electromechanical equipment,

7-To provide dynamic improvements in production, management, service offerings, diversified remote inspections, self employment and other areas
