| Abstract: | The design of a binary-phase shift-keyed (BPSK) spread-spectrum chip set with an integrated CAD environment called VANDA is described. VANDA uses the functional compiler concept to integrate system and physical designs, thus allowing complex high-performance integrated circuit chips to be implemented easily. Three functional compilers have been designed and implemented for the design of a spread-spectrum transceiver: a pseudonoise (PN) generator compiler, a direct digital frequency synthesizer (DDFS) compiler, and a Costas loop compiler. Three test chips for a BPSK digital intermediate frequency (IF) spread-spectrum system generated by these compilers have been fabricated and tested. Details of each of the functional compilers and the test chips are described. In addition, the measurement results for digital IF transceiver test boards constructed using these chips are presented |
