receive channel
5.Such a scenario can be abstracted from quantum channels and noisy channels: two communicants. Alice and Bob, and an adversary, Eve, receive three variables X, Y, Z which are distributed according to some probability distribution P~. Then Alice and Bob begin secret-key agreement over a public channel.
7.Abstract: By comparing the channel capacities hetwem orthogonal space-time block coding and multi-antenna array system over Rayleigh fading channel,some capacity loss for orthogonal space-time block coding is obtained,which is a function of the code rate,the rank of channel matrix and the number of transmitter and receive antennas,although the system of orthogonal space-time block codes is simple and easy to implemented.If is also shown that there is no capacity loss only if both the code rate and the channel matrix rank are all one.
8.The system introduced by this article adopts 8051 MCU as microprocessor and exploits emanated infrared channel to consist of infrared real-time distributed dolly control system. The designed base-station and substation(dolly controler) both have infrared interface which can beam and receive infrared signal.
