  • • Tín hiệu truyền qua kênh truyền sẽ bị ảnh hưởng bởi nhiễu, can nhiễu, fading… là tín hiệu đầu thu bị sai. • Mã hóa kênh: dùng để bảo vệ dữ liệu không bị sai bằng cách thêm vào các bit dư thừa (redundancy). • Ý tưởng mã hóa kênh là gởi một chuỗi bit có khả năng sửa lỗi • Mã hóa kênh không làm giảm lỗi bit truyền mà chỉ làm giảm lỗi bit dữ liệu (bảng tin) • Có hai loại mã hóa kênh cơ bản là: Block codes và Convolutional codes...

  • Convolutional codes are linear. Therefore, the Hamming distance between any pair of code sequences corresponds to the Hamming distance between the allzero code sequence and some nonzero code sequence. The nonzero sequence of minimum Hamming weight diverges from the allzero path at some point and remerges with the allzero path at some later point

  • A Privacy Homomorphism (PH) Technique is being used in the system to provide prominent security features to client. Here, PH emphasise to resolve the security of query processing from client side, cloud, with the kNN on R-tree index query and distance re-coding algorithm. PH technique support to leverage performance parameter in cloud computing.

  • My objective in writing this book was to produce a general, comprehensive textbook that treats all the essential core areas of cryptography. Although many books and monographs on cryptography have been written in recent years, the majority of them tend to address specialized areas of cryptography. On the other hand, many of the existing general textbooks have become out-of-date due to the rapid expansion of research in cryptography in the past 15 years.

  • Pandemic planning should consider the need for stockpiling of essential supplies. Discuss with key suppliers a plan for regular shipments in the event of shortages or disruptions in transportation systems. Shortages may occur because of disruptions in transportation systems or inability of suppliers to meet demands because of their own staff shortages. Canadian supplies travel long distances by truck, train and aircraft and are vulnerable to any disruption.

  • Weighted graph We can add attributes to edges, We call the attributes weights; Then if we want the shortest travel distance between cities an appropriate weight would be the road mileage; If we are concerned with the dollar cost of a trip and went the cheapest trip then an appropriate weight for the edges would be the cost to travel between the cities.

  • For reliable communications to take place on a network, things like the physical method of signaling and the meaning of each signal or series of signals must be defined ahead of time. Create a simple physical network and agree on some basic rules for communication in order to send and receive data. This will be a digital network based on the American Standard Code for Information Interchange (ASCII). It will be similar to the old telegraph Morse code-based systems. In these older systems the only means of communicating over long distances was by sending a series of dots and dashes...
