This paper presents a frequency-domain analysis of the noise and distortion terms produced
by a digital RF modulator that uses pulse width modulation (PWM) for the amplitude …

Typical radar transmitter signals are frequency-modulated with pulsed constant-amplitude
envelopes in order to optimize radio-frequency power amplifier (RFPA) efficiency, which …

Digital pulsewidth modulators are used to transform nonconstant amplitude signals into
pulsed signals, such that the information lying in the signal amplitude is encoded in the …

Digitally modulated power amplifiers (DMPA) are a promising architecture for practical and
highly efficient software-defined radio transmitters. Signal encoding schemes for DMPAs …

This paper describes a transceiver simulator with two different configurations: one
corresponding to wireless LTE standard and other to Mobile WiMAX standard. Both include …

This paper presents a time-domain characterization of non-linear microwave devices driven
by wideband modulated signal. A fully calibrated 4 channel time-domain measurement …

This paper deals with the implementation of a Nonlinear Interference Suppressor (NIS) into
a wireless LTE transceiver. This within the context of high energy efficient multi-standard …

Communications systems with single carriers can be seen as a simple system. Despite their
simplicity, they do have drawbacks such as low bit rate and the need for complex equalizers …
