Software Defined Radio New Trends for Wireless Transceivers

Several techniques are now being utilized to ensure efficient communications across the jam-packed radio spectrum. Chief among them are SDRs, which enable software to dynamically control communication parameters such as the frequency band, modulation type and data rates. SDR leads to delaying the binding of design decisions until execution time. Hence, the designers can incorporate the latest developments that enable them to improve the performance of the developed systems. Additionally, SDR allows both flexibility and maintenance simplicity, as most upgrades can be done by loading new software, rather than changing hardware modules. Frequency hopping is an important stage among variety of SDR applications and footprints. Although frequency hopping is not a new technique, designers are continually striving to increase the hopping rates to improve and reinforce performance in multi-path and fading channels.
