FPGA-based signal processors are used in a wide range of signal processing applications for reasons of performance, economy, flexibility and power consumption. Software-defined radios (SDRs) are highly configurable hardware platforms that provide the technology for the rapid expansion of the future-generation digital wire communication infrastructure. Many sophisticated signal processing tasks are performed in an SDR, including advanced compression algorithms, power control, channel estimation, equalization, direct error control, adaptive antennas, rake processing in a WCDMA system, and protocol management. Field-programmable gate arrays (FPGAs) outperform digital signal processors (DSPs), through hardware execution of a wide range of parallel algorithms. FPGAs are especially suitable for embedded systems because, in addition to an area of reconfigurable logic elements, they can also incorporate large amounts of memory, high speed DSP blocks, clock management circuits, high speed I / O (I / O) as support for external memory and high-speed networks and communication bus standards.
Software-defined radios (SDRs) are highly configurable hardware platforms that provide the technology for rapid expansion of the third (and future) generation of digital wireless communications infrastructure. Although there are a plethora of silicon alternatives available to implement the various functions in an SDR, field programmable gate arrays (FPGAs) are an attractive option for many of them.
