National Cheng Kung University ABSTRACT Cooperative network coding has been proposed as an effective solution to improve system performance. Through collaborative network coding in the intermediate node(s) instead of direct forwarding‚ the transmission reliability‚ efficiency‚ and security can be enhanced significantly. Although extensive research activity on the cooperative network coding has been reported in the literature‚ most works focused only on their technical analyses‚ and no effort

is Physical Layer. The physical layer is what the name implies‚ i.e. physical components of a network. This layer is concerned with transmission and reception of unstructured raw data over physical medium. The function of physical layer is to take binary information from higher layers‚ translate it into transmission signal‚ transmit the information across transmission medium‚ receive this

SUBJECT: ANTENNAS AND WAVE PROPAGATION 1. Define an antenna. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice versa. Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the
