FPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects

Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...

A Comparative Study for Performance and Power Consumption of FPGA Digital Interpolation Filters

The development of FPGA-based digital signal processing devices has been gaining attention. Researchers seek to reduce power consumption and enhance signal processing quality in these devices with given resources and spatial limits. Hence, there is a need to investigate both the capability and the power consumption associated with the various digital filtering schemes commonly used in FPGA-base...

Efficient Hardware Implementation of Digital Filters using Distributed Arithmetic (DA)

The FPGA (Field Programmable Gate Array) constitute of many programmable modules like Configuration Logic Blocks (CLBs), Block Random Access Memories (BRAM), DSP 48 blocks and Input/output (I/O) modules. The CLBs are the main programmable logic units which consist of different number of logic slices and each slice contains different number of LUTs and flips flops depending upon the FPGA device ...
