– A cross-coupled relaxation oscillator has two outputs of the same frequency, which are in quadrature. In this paper a comparative study of the phase noise in a cross-coupled re...
— A novel methodology for reducing the phase noise of cross-coupled LC tank VCO is presented, verified and measured. The fundamental relationship between the phase noise and the ...
— A 3.5-5.3 GHz, low phase noise CMOS VCO with switched tuning for multi-standard radios is presented in this paper. Design of low phase noise and small amplitude variations acro...
This paper presents a fully integrated 1-V, dual band, fastlocked frequency synthesizer for IEEE 802.11 a/b/g WLAN applications. It can synthesize frequencies in the range of 2.4 ...
— A very promising way to achieve high spectral efficiency in wireless communication is the use of multiple transmit and receive antennas. However, in combination with multicarr...
— The use of multiple transmit and receive antennas in combination with multicarrier modulation, e.g. MIMO-OFDM, is a very promising technique for future wireless communication s...

Abstract— OFDM systems are susceptible to receiver impairments such as IQ imbalance and phase noise. These impairments can severely degrade the achievable effective signalto-nois...
—The growing demand for reliable communications leads to the need for very large mean time to lose lock (MTLL) of PLL based synchronization subsystems. These large MTLLs, of the ...
— In this paper we discuss the effect of phase noise at both, transmitter and receiver in an OFDM system. We study an iterative equalization system at the receiver. The system is...
—We consider a distributed wireless network where amplify-and-forward relays assist the communication between multiple source/destination pairs. To provide a global phase referen...
