Random transceiver networks

Random transceiver networks

Consider randomly scattered radio transceivers in Rd, each of which can transmit signals to all transceivers in a given randomly chosen region about itself. If a signal is retransmitted by every transceiver that receives it, under what circumstances will a signal propagate to a large distance from its starting point? Put more formally, place points {xi} in Rd according to a Poisson process with...

Reconfigurable cognitive transceiver for opportunistic networks

In this work, we provide the implementation and analysis of a cognitive transceiver for opportunistic networks. We focus on a previously introduced dynamic spectrum access (DSA) cognitive radio (CR) solution for primary-secondary coexistence in opportunistic orthogonal frequency division multiplexing (OFDM) networks, called cognitive interference alignment (CIA). The implementation is based on ...

Efficient Design of Transceiver for Wireless Body Area Networks

This paper investigates the efficient design of the PHY layer architecture for wireless body area networks (WBAN), which targets on ultra-low power consumption with reliable quality of service (QoS). A low cost baseband transceiver specification and a data processing flow are proposed with a comparatively lowcomplexity control state machine. A multifunctional digital timing synchronization sche...

Realizing a CMOS RF Transceiver for Wireless Sensor Networks

The choice of the CMOS radio frequency (RF) transceiver architecture affects the design of the whole system and is thus a fundamental one. In order to make a good choice, several factors have to be considered, the most important ones being: performance, power consumption, die size, cost, integration level, and time-to-market. The minimum required performance is dictated by the IEEE802.15.4 stan...
