  1. SOFTWARE DEFINED RADIO – DSSS CDMA Digilogic’s Direct Sequence Spread Spectrum Radio provides highly reliable communications with high resistance to interference and interception. The radio establishes a point to point communication link leveraging the spread spectrum and CDMA techniques. Prototyped based on the NI SDR Platform, the radio offers flexibility both in terms of hardware and software. Software-defined radio (SDR) is a radio communication system in which components that were previously implemented in analogue hardware are now implemented as software on a personal computer or embedded system. While the notion of SDR is not new, the fast growing capabilities of digital electronics enable numerous procedures that were previously only theoretically conceivable. Page 1 of 4

  2. Software-defined radios can be adjusted "on-the-fly," which means the universal communication device will reconfigure itself based on the environment. It could bea cordless phone one minute, a cell phone the next, a wireless Internet device the next, and finally a GPS receiver. Software-defined radios may be simply upgraded with new functionalities. In reality, the upgrade might be given over the air. Software-defined radios enable simultaneous communication with several channels. Create new types of radios. Smart radios or cognitive radios (CRs) can monitor the use of the RF spectrum in their immediate vicinity and tune themselves for optimal performance. Highlights: Direct-Sequence Spread Spectrum (DSSS) Technique CDMA Architecture to achieve additional Processing Gain BPSK/QPSK Modulation Scheme Full-duplex Communication with FDD Mode 2-Finger Rake Receiver for multipath mitigation Up to 20 km Ling of Sight (LoS) Range Up to 20 dB Jamming to Signal (J/S) Ratio Built-in application for text messages and FTP Page 2 of 4

  3. Applications for SDR and DSSS CDMA: Wireless Communication Systems: SDR is commonly employed in current communication systems such as mobile phones, Wi-Fi networks, and satellite communication. Military Communications: SDR's flexibility and security qualities make it ideal for military applications that require adaptability and secure communication. SDR allows the integration of many IoT devices by supporting multiple communication protocols. Satellite Communications: DSSS CDMA is used in satellite communication systems to improve dependability and reduce interference. The merging of Computer Driven Radio and the DSSS CDMA has made important contributions to the world of mobile communications. SDR's versatility and the DSSS CDMA's resilience make them vital elements in a wide range of uses from common mobile phones to crucial defence and satellite communication networks. Page 3 of 4
