Achieving the highest possible performance from circuits used in third-and fourth-generation wireless systems is driving a tighter integration of previously disparate tools. Certainly, a level of software synergy is essential when designing circuits for use in today`s wireless systems that employ higher-order modulation techniques together with ad

vanced technologies, such as Orthogonal Frequency Division Multiplexing (OFDM), multiple-input multiple-output (MIMO), and digital predistortion (DPD) circuits, to name a few. As this article illustrates, AWR`s Visual System Simulator (VSS) and National Instruments` LabVieW graphical programming environment are now co-simulating to better enable designers to analyze, optimize, and verify complex RF circuits, subsystems and digital signal processing within a unified framework. Before looking more closely into specific design scenarios, it is important to understand how this new and cohesive VSS/LabVIEW co-simulation environment works. The integration of VSS and LabVIEW is enabled via a new LabVIEW block within VSS. The simulation is driven by VSS and the LabVIEW block provides the interface to LabVIEW, allowing the exchange of data and parameters between the two platforms (Figure 1). This new block invokes a LabVIEW virtual instrument (VI) which in turn performs digital signal processing functions programmed through palettes provided in the graphical programming environment. This interface provides flexible configuration options with user-defined mapping of VSS nodes and parameters to the VI input and output ports. Multiple LabVIEW blocks may be placed on a VSS system diagram so that multiple VIs are executed at the same time. This integration offers VSS and LabVIEW users increased capabilities, such as expanded math and...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
