As wireless communication systems evolve towards higher data rates
and increased complexity, the demand for efficient signal processing
algorithms also rises. Memoryless predistortion techniques play a
crucial role in mitigating nonlinear distortions in RF power amplifiers,
ensuring high-quality transmission. This study presents a novel
multichannel FPGA implementation of a real-time signal processing
algorithm for memoryless predistortion in wireless communication
systems. The proposed methodology leverages parallel processing and
hardware acceleration to achieve high throughput and low latency. The
key contribution lies in the efficient utilization of FPGA resources to
implement the predistortion algorithm across multiple channels,
enabling real-time operation with minimal hardware overhead.
Experimental results demonstrate the effectiveness of the FPGA-based
implementation in compensating for nonlinear distortions in RF power
amplifiers. The system achieves significant improvements in signal
quality and spectral efficiency, paving the way for enhanced
performance in wireless communication systems.
