New multiple-transmitter, multiple-receiver (MTMR) systems promise huge gains in data capacity that cannot be ignored by a wireless industry that desires to increase the data capacity for subscribers in an increasingly congested frequency spectrum. Design of such systems, however, will require an entirely new approach to channel modeling, since traditional techniques have dealt with single ante...

-In this paper, we introduce a new mixed priority scheme that utilizes the logarithmically equi-spaced random transmitter power levels (LESRTPL) model to control the assignment of the transmitter power levels, assigned to each priority class, adaptively. Packets, of different priority classes contending simultaneously over the wireless channels to capture a contention slot, will transmit using ...

This paper deals with the modified wireless power transmission system for biomedical implanted devices. The system consists of efficient class-E power amplifier and inductive power links based on spiral circular transmitter and receiver coils. The model of the class-E power amplifier operated with 13.56 MHz is designed, discussed and analyzed in which it is achieved 87.2% of efficiency. The ind...

Radio Frequency (RF) fingerprinting is a security mechanism inspired by biological fingerprint identification systems. RF fingerprinting is proposed as a means of providing an additional layer of security for wireless devices. RF fingerprinting classification is performed by selecting an “unknown” signal from the pool, generating its RF fingerprint, and using a classifier to correlate the recei...

Applications In this paper A single chip 2.4GHz low power CMOS receiver and transmitter for WPAN applications are implemented and measured. The receiver uses a low-IF architecture with a polyphone filter and transistor linearization technique to improve linearity per power, and the transmitter adopts a ROM based direct-conversion architecture for low power consumption and high integrated densit...

In the last 20 years, research into and clinical use of wireless ingestible capsules (WIC) has increased, with capsule endoscopy being most common application in practice. Additionally, there been an increased interest sensing capsules. To maximize usefulness information provided by these devices, it is crucial to know their location within gastrointestinal tract. The main WIC localization meth...

This correspondence considers multiple-input single-output (MISO) wireless systems with equal gain transmission (EGT) at the transmitter and maximum ratio combining (MRC) at the receiver. In such systems, the receiver feedbacks the elemental phases of beam-forming vectors to the transmitter. Due to finite feedback rate, the elemental phases of beam-forming vectors have to be quantized effective...
