SUBSCRIBER UNIT FOR WIRELESS DIGITAL TELEPHONE SYSTEM Russian patent published in 2004 - IPC

FIELD: wireless digital telephone systems.

SUBSTANCE: subscriber unit has data transfer processor connected through series-interconnected coder/decoder and interface to subscriber telephone set and also to data input of modulation/demodulation processor whose data output is connected through series-interconnected transmitting memory unit, interpolator, programming logic matrix, and digital-to-analog converter to first input of multiplier; output of the latter is connected to antenna through transmitting unit that has switch connected to receiving unit whose output is connected to data input of modulation/demodulation processor through series-interconnected sampling unit, analog-to-digital converter, and memory receiving unit; it also has master oscillator connected to transmitting and receiving units and series-connected frequency divider, synchronization unit, and blanking signal shaper; frequency divider input is connected to master oscillator; output of blanking signal is connected to second input of multiplier, and output of modulation/demodulation processor is connected to other input of synchronization unit.

EFFECT: improved design.
