This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel ...

This article describes Atmel’s FingerChip technology for electronic fingerprint sensing that combines the advantages of small size, low cost, high accuracy, zero maintenance, low energy consumption and portability. This technology has applications in a wide range of fixed and portable secured devic ...

The Staged Event-Driven Architecture (SEDA) is a new design for building scalable Internet services. SEDA has three major goals: To support massive concurrency, on the order of tens of thousands of clients per node To exhibit robust performance under wide variations in load and, To simplify the ...

SCSI-2也称为Fast－SCSI，传输速率为10MB／s。 后采用扩展总线宽度来增加数据流量的方式，提高整 体传输速率，于是SCSI－2规定了16位、32位数据总 线，使传输速率进一步提高为20MB／S，也就是Wide －SCSI，或是称作Fast SCSI－2。 Wide－SCSI采用4 位定址，使可连接的设备达到了15个。在接口电缆上， 为兼容SCSI－l所使用的 ...

The goal of this library is to make ODBC recordsets look just like an STL container. As a user, you can move through our containers using standard STL iterators and if you insert(), erase() or replace() records in our containers changes can be automatically committed to the database for you. The lib ...

In this paper, we provide an overview of the security concerns introduced by wireless LANs, current approaches to wireless LAN security, their limitations, and the weaknesses of various “band aid” security solutions. We conclude by describing how the ReefEdge Connect System provides a comprehensiv ...

This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and ...
