Design and implementation of a frequency hopping spread spectrum testbed

Includes bibliographical references (leaf 75)This graduate project describes the design and implementation of a frequency hopping spread spectrum (FHSS) communication testbed. Simulink was used to model this FHSS system that includes a spreading code synchronization mechanism and a graphical user interface. The perfmmance of the system, as measured by the bit error rate, was compared to known results to verify that it operates correctly both with and without jamming. The PN code acquisition system was shown to conectly acquire PN codes for values ofEb/No down to 6dB. The PN code tracking system was tested to work at values of Eb/No down to 0 dB. This model can now be used in conjunction with a number of software radio systems to implement an actual spread spectrum link
