Mobile communication systems currently use linear modulation schemes for effective usage of the frequency spectrum resource. Signals that use linear modulation schemes, however, such as QPSK, and 16- and 64-QAM, have a high peak-to-average power ratio and the signal envelope is changed severely. Therefore, modern mobile communication systems require...

The market demand for low cost and high performance wireless communication systems, including cellular phones, wireless local area networks (WLAN) and wireless personal area networks (WPAN), has attracted heavy investment and intensive research in the area of integrated RF transceiver design. 1–9 Unlike a traditional discrete component radio design,...

Electromagnetic signals are used to transmit information in the form of amplitude, frequency, phase and time duration of an oscillation. In many cases, they must be amplified from a low to a higher power level by an amplifier having special basic characteristics, such as sufficient gain within a specific...

Phase noise is a frequency domain measure of the short-term stability of an oscillator. It is measured and specified as noise power, relative to carrier power, in a one Hz bandwidth at a given frequency offset. Typically, for a communication system oscillator, the phase noise requirement is specified for...
