† Currently Research Laboratories *1 LTE: Extended standard for the 3G mobile communication system studied by 3GPP. Achieves faster speeds and lower delay than HSPA. *2 OFDMA: A radio access scheme that uses Orthogonal Frequency Division Multiplexing (OFDM). OFDM uses multiple low data rate multi-carrier signals for the parallel transmission of wideband data with a high data rate, thereby imple...

Pharmacological and behavioral studies suggest that spinal and -opioid antinociceptive systems are functionally associated with ovarian sex steroids. These interactions can be demonstrated specifically during pregnancy or hormone-simulated pregnancy (HSP). The analgesia associated with both conditions can be abolished by blockade of either spinal -opioid receptors or -opioid receptors (DOR). Fu...

This paper focuses on present day scenario of communication through MIMO technology. MIMO systems are high in demand because of their versatility features. They offer high data rates, throughput, different frequency of operability as per demand and many more. Because of this it finds application in LTE, WiMax, HSPA+ and other wireless communication and latest technologies. Keywords-MIMO, Antenn...

Cooperated multi-point technique in HSPA system has not been paid attention until the Single Frequency Dual Cell (SF-DC) mode, where one user equipment (UE) may be served by dual NodeBs simultaneously in the single carrier frequency network, is proposed recently. In the previous research, the system-level performance with SF-DC operation had not been studied comprehensively. The main contributi...

We present a Universal Rate Control Protocol (URCP), which provides applications with fair and full link utilization while operating at low delay and loss levels as needed by interactive real-time communications (RTC) applications across a range of complex networks in use today, such as Wi-Fi hotspots, 4G (HSPA+), and WiMAX. As opposed to many existing rate control techniques which are speciall...

The purpose of writing this article is to present and study femtocellular technologies for mobile cellular networks. With the introduction fourth 4G-LTE fifth 5G generation systems, term femto cell began be strongly mentioned. Femto cells are very small that provide service users with a home base station connect telecommunications operator's network. femtocell mainly looking ever higher data ra...

The objective is to deliver a low-cost telemedicine platform which will allow for reliable remote diagnosis m-health applications such as emergency incidents, mass population screening, and medical education purposes. The performance of the proposed system is demonstrated using f...

The 3rd Generation Partnership Project (3GPP)’s Release’8 Long Term Evolution (LTE) defines the next step of 3G technology. LTE offers significant improvements over previous technologies such as UMTS/HSPA. Higher downlink and uplink speeds, lower latency and simpler network architecture are among the new features that are provided. One of the central features that provides transmission robustne...

Wideband Code Division Multiple Access (WCDMA) technology has emerged as the most widely adopted third generation (3G) air interface. 3GPP Release 7 (HSPA+) WCDMA systems introduced two features Higher Order Modulation (HOM) and Multiple Input Multiple Output (MIMO). MIMO improve the throughput in wireless medium. It achieves a higher spectral efficiency. This paper focuses on the performance a...
