Abstract :
A software defined radio with the analog stage using the direct conversion principle and the digital stage using a DSP demodulator has been developed. The developed receiver realizes a multi-band characteristic of the 1.5 GHz and 1.9 GHz bands and a broadband characteristic up to 10 MHz together with a demodulation function of π/4-QPSK and GMSK, and the overall receiver performance was confirmed
