The development of signal processing and coding techniques for magnetic recording channels has taken place in an environment of escalating demand for higher data transfer rates and storage density. The error probability of many magnetic-recording systems may be characterized in terms of the differences between the sequences that may be recorded. In fact, the bit-error rate is often dominated by a...
WiMAX is the latest technology that has promised to offer broadband wireless access over long distance. The throughput of wireless communication such as WIMAX depends on number of parameters. These parameters include: packet size, transmission rate, signal to noise ratio, modulation techniques and channel conditions. All these variables are discussed using simulation, certain graphs have obtain optimum...
Cognitive radio (CR) is regarded as an emerging technology to utilize the scarce RF (radio frequency) spectrum in opportunistic manner to increase the spectrum efficiency. However, major challenge to successful operation and realization of CR system is the identification and detection of primary user signals in the wide band regime to identify spectrum opportunities reliably and optimally. Several...
The frequency of operation for different RFID applications changes depending on the constraints associated with the application, some of the blocks of the RFID tag can be designed, which works for multi-standard RFID frequencies such as 13.56 MHz, 915 MHz and 2.45 GHz. Basic block diagram for RFID tag for biomedical applications is considered in this work. Power feeding block and the digital block...
