Use of wireless telecommunication system with code channels division based on modified pseudorandom gold sequences for the information transmission from surveillance cameras

摘要

The authors propose the method of building telecommunication systems to transmit information from surveillance cameras in the complex system ???Smart house??? based on the modified Gold pseudorandom sequences with the length of 15+1 impulses and 4-position PSK signal, which makes possible to reduce the required radio channel bandwidth on the working frequencies in 12.57 times with the given quantity of coded channels in comparison with the method of time division. It's shown that the use of proposed system design method allows to get integral coefficient of efficiency value equal to 16.3 dB in comparison with the method of time division of the information channel.
