A software characterized radio framework, or Software Defined Radio SDR, is a radio correspondence framework where parts have ordinarily been executed in programming rather than equipment (e.g. blenders, channels, enhancers, modulators/demodulators, finders, and so forth.). Here the execution of our ongoing programming characterized radio framework is finished by field programmable door exhibits....
Combined TMS320C6455DSP and FPGA data acquisition platform, this paper describes the C6455 DSP Enhanced Direct Memory Access (EDMA) hardware architecture and configuration methods, focusing on the EDMA applied in two ways, both of which increase the transmission DSP data transfer speed, enhanced the DSP processing power to meet the physical layer of TD-LTEA complex algorithms in real time operations...
This paper presents a new low cost GNSS Software (SW) receiver for Microsatellites. TES Electronic Solutions (Bruz, FRANCE) has been chosen by CNES for developing and manufacturing this equipment which should be tested on board the scientific microsatellites named TARANIS and MICROSCOPE that will be launched in 2013 and 2014. The GNSS receiver under development is a high-performance equipment specially...
A low-complexity systolic-array architecture is proposed for obtaining multiple(N) broadband radio-frequency (RF) beams in smart antenna arrays. The N-beam 2D IIR digital filter is based on the concept of 2D passive ladder network resonance, leading to differential-form implementations which are highly-suitable for RF throughput levels. The proposed beamformers are converted to differential-form discrete...
In this paper, a practical design of fingerprint recognition combined with smart card verification for two-factor authentication system is proposed. Our core algorithm processing unit is based on TI's TMS320VC5510, a high-performance, low-power and fixed-point DSP. Feature data storage is completed by RF card, which is different from ordinary solution. When DSP finishes the feature extracting, features...
CalRadio 1 is an open 802.11b-compatible development platform, designed and developed at UCSD with the aim of providing the research community with an open and fully reprogrammable board for experimental purposes. In this work we describe the hardware and software architecture of the board and we provide an accurate analysis of the limiting performance achieved by CalRadio 1 in comparison with commercial...
