The reconfigurable multi-function matrix operation (MFMO) module circuits including eigen-value and eigen-vector decomposition (EVD), QR factorization (QRF), linear system solver (LLS), and matrix multiplier (MM) for the software defined radio and cognitive applications are designed using coordinate rotations digital computer (CORIDC) algorithm. The processing time for each scalable N??N MFMO module...
The software defined radio (SDR) channel simulator is designed and implemented in the FPGA for various wireless communication systems. The dedicated short range communications (DSRC) and ultra-wideband (UWB) channels are carried out to observe the characteristics of multi-path fading channels and validate the correctness of the SDR channel simulator. The hardware reconfiguration of the fading channel...
The software-defined radio (SDR) channel simulator is designed for testing the baseband transceiver of various wireless communication systems. The SDR architecture and the reconfiguration scheme used for changing the channel conditions and reconfiguring the hardware of the processing modules in the SDR channel simulator are presented. The simulator is capable of simulating four multipath fading channels...
The reconfigurable feature of software defined radio (SDR) architecture gives rise to reusability, scalability, and power efficiency. Reusability of hardware supporting multiple modes of DBF strives for compactness and efficient processing power, which are important issue for micro-satellite synthetic aperture radar (SAR) systems. In this paper, according to the SDR architecture, a digital beamforming...
The reconfiguration scheme and channel algorithms of the software defined radio (SDR) channel simulator is designed for testing the base band transceiver of various mobile radio systems. The flexibility in selecting a combination of waveform and fading channel software modules and setting the system parameters is the main feature of the SDR channel simulator. An example of the SDR channel simulator...
