The imaging laser radar is fine measure equipment for TAN with the ability to get the high precision 3D terrain. A 3D terrain matching processor was needed to be designed for the specifical application. In this paper, base on the specialty of the imaging laser radar, the3D terrain matching processor was designed, with scheme of DSP+FPGA calculating engine, multi-level memory system, flexible parallel...
Correlative minimum shift keying (MSK), a second order polynomial modulation scheme known as tamed frequency modulation (TFM), is a constant envelope type of modulation with a perfect peak to average power ratio (PAPR), besides the property of low out of band power. We apply the linearized TFM to the single carrier transmission with frequency domain equalization (SC/FDE) concept. We then obtain a...
Fast Fourier Transform (FFT) is the most basic and essential part of Software Defined Radio (SDR). Therefore, designing regular, reconfigurable, modular and low hardware complexity FFT computation block is very important. A single FFT block should be configurable for varying length FFT computation and also for computation of different transforms like DCT, DST etc. In this paper, the authors analyze...
