The IEEE 802.16 standard, defining the Worldwide Interoperability for Microwave Access (WiMAX) for Metropolitan Area Network (MAN). The IEEE 802.16 standard, includes specification for the Medium Access Control (MAC) and Physical (PHY) layers, is designed to serve all kinds of traffic. The standard is equipped with signaling and bandwidth allocation(More)
BACKGROUND Meckel's Diverticulum is the most commonly encountered congenital anomaly of the small intestine, occurring in approximately 2% of the population. Occasionally Meckel's diverticulum harbors neoplasms. CASE PRESENTATION A 65 year old gentleman, presented with a pelvic mass. On exploratory laparotomy, it turned out to be gastrointestinal stromal(More)
In recent years, there has been an explosive demand for wireless and portable applications, which resulted in more flexible communication systems that can handle various standards in different environments. In an ideal software radio, the data conversion occurs immediately after the signal received from the receiving antenna.. This paper presents(More)
In the present scenario, wireless technologies require an advanced receiver which supports multi-standard and multi-mode transmission. In an ideal software radio, the data conversion process occurs immediately after the antenna in the receiver chain..A/D conversion at an early stage plays an important role for achieving such flexibility at the receiver.(More)
Jitter is the limiting effect for high speed analog-to digital converters with high resolution and wide digitization bandwidth, which are required in receivers in order to support high data rates. The rapid development of digital wireless system has led to a need of high resolution and high speed analog to digital converter. The proper selection of data(More)
The drastic escalation in the ways and means by which user need to exchange information, replacing RF unit effortlessly and cost-reduction has become important. Software Defined Radio (SDR) tools provides the flexibility, price competence and influence to make communications possible, with extensive accomplishment benefits offered by the RF operators and(More)
This paper presents the effect of timing jitters on the performance of sigma delta ADC for SDR mobile receivers. The time-varying behavior is caused by the non-stationary nature of the clock jitter process. Jitter is the limiting effect for high speed analog to digital converter with high resolution and wide digitization bandwidth, which are required in(More)
