This paper present the relationship between the performance of the analog-to-digital converter (ADC) and the digital FPGA and/or IC based π/4 DQPSK. As such, the ADC resolution and the ADC sampling rate are analyzed. As a result, ADC parameters for 20 Mb/s data rate were selected.
This paper presents a method of calculating the minimal required transmission period for control messages and power margin for MANET with constrained resources, namely for communication and control systems on-planet robotic systems. For a system with ten robotic devices, with velocities of 10 cm/s, the sufficient power margin for worst case scenario will be… (More)
This paper presents an analog-controlled feedback for predistortion of switched mode GaN power amplifier with PAPR reduction technique. The nonlinearity control scenarios and algorithms are described. After the statistic simulation for different feedback delay the frequency dependent feedback loop was analyzed for implementing the model which enables to… (More)
