Spread-spectrum Communication System
Machala, Pavel ; Šimek, Milan (referee) ; Číž, Radim (advisor)
The thesis focuses on issues around communication system with the Direct Spread Spectrum Signal Signal. This work outlines the theoretical analysis of this technique and subsequently is created a communication system concept. The device concept is adjusted so that the device can be used as a laboratory device, presenting the spreading technique. This thesis offers a comprehensive and detailed description of the communication system construction, including design of transmitter, receiver and a common transmission channel. In conclusion are stated the results of devised communication system.

BPSK transmitter for 435 MHz
Hocz, Jan ; Šebesta, Jiří (referee) ; Urbanec, Tomáš (advisor)
This thesis deals with basics of BPSK modulation. Another part compares different integrated circuits of transmitters able to use BPSK modulation on a given frequency, the choice of suitable microprocessor and transistor. Another part describes the connection of individual integrated circuits on printed circuit board and their realization. In the following section, the software and individual commands for transmitter control are described. In the final section is the functionality checked and the basic parameters reached are presented.
