Coding Techniques for Amplifier Nonlinear Distortion Mitigation

In this section, the popular coding techniques for mitigating nonlinear distortion caused by HPA are reviewed. The three most popular techniques in the literature are partial transmit sequences (PTS), selective mapping (SLM), and block coding. Note that each of these methods require side information to be transmitted to the receiver.

Partial Transmit Sequence Techniques

PTS was first introduced by S. Muller and J. Hüber [21]. The concept is fairly simple and effective. The following notation is used throughout this development. The nth transmit symbol modulating the jth subcarrier is denoted by xj(n). The input data block at time instance n is formed as
