"In this paper we will design a novel idea for a single chip wireless QPSK receiver without resort to extra resonator based reference. In contrast to conventional architectures, the receiver recovers the RF carrier frequency directly from the incident radio signal for frequency down conversion. Meanwhile, the model designed will accomplish frequency acquisition and also phase and frequency tracking as well as QPSK demodulation simultaneously. This design is a 2.4GHz reference-less single chip wireless receiver for QPSK demodulation .The designed receiver will accomplish Local Oscillator carrier recovery and data demodulation directly from the RF received signal without resort to resonator based reference, such as crystal oscillator but by using the designed Carrier recovery loop.
