Probability-based clipping of full parallel 128-point FFTs is proposed, which offers 3-bit resolution reductions of FFT and achieves 28% logic resource usage reduction and highly accurate stage-dependent bit resolution maps. Results are verified over FPGA-based Coherent Optical OFDM transmission systems.
In this paper, a six-cavity High power continuous wave magnetron (HPCWM) is built by MAGIC Code. The power and frequency of the HPCWM with different anode voltages and magnetic field are obtained. A corresponding HPCWM, which is operated with different magnetic field, is performed experiment measurement. Both the simulation and experiment results are compared with each other, which is very helpful...
This paper presents an exponentially tapered dielectric loaded probe. The backlobe of the probe is significantly reduced without increase the aperture size. The VSWR is less than 1.4 in the whole X band. The E field and current distribution are presented, which indicate the principle of the novel probe. The nominal radar cross-section (RCS) is below −25 dBsm in the whole frequency range. The performance...
Antenna phase center (PC) is defined as a location from which radiation is considered to emanate. Active elements of a log-periodic dipole array (LPDA) antenna shift during a frequency sweep, which causes PCs to change with frequencies. This results in an undefined actual distance between the radiation and reception points, and thus forms a dominant error for LPDA antenna calibration. This paper concentrates...
