This article proposes a nonlinear compensation technique for long‐term evolution downlink signals based on the memoryless solid‐state power amplifier model, which provides a simple and effective linearization technique at the receiver side, allowing a reduction in the error vector magnitude measured characteristics. The error vector magnitude per subcarrier is analyzed for different appropriate resource blocks allocations in the long‐term evolution signal to examine the distortion due to the nonlinear effects produced by a power amplifier in the experimental setup. © 2011 Wiley Periodicals, Inc.
