Abstract: into the wavelet packet transform (WPT) modulation scheme for Multiple Input Multiple Output (MIMO) band-limited systems is presented. The implementation involves using the WPT as the base multiplexing technology at baseband, instead of the traditional Fast Fourier Transform (FFT) common in Orthogonal Frequency Division Multiplexing (OFDM) systems. An investigation for a WPT-MIMO multicarrier system, using the Alamouti diversity technique, is presented. Results are consistent with those in the original Alamouti work. The scheme is then implemented for WPT-MIMO and FFT- MIMO cases with extended receiver diversity, namely 2 ×Nr MIMO systems, where Nr is the number of receiver elements. It is found that the diversity gain decreases with increasing receiver diversity and that WPT-MIMO systems can be more advantageous than FFT-based MIMO-OFDM systems.

On the Optimization of Iterative Clipping and Filtering for PAPR Reduction in OFDM Systems
TL;DR: This paper applies an adaptive clipping threshold to the LM scheme to improve the performance of the simplified OICF (SOICF) and shows significant reduction of the PAPR problem compared with the earlier SOICF scheme albeit with some degradation in the bit error ratio performance.

A New Approach to Iterative Clipping and Filtering PAPR Reduction Scheme for OFDM Systems
TL;DR: This work introduces a uniform distribution approach to solving the PAPR reduction problem of OFDM signals and uses Lagrange multiplier (LM) optimization to minimize the number of iterations involved in an adaptive fashion.

On the Application of Raised-Cosine Wavelets for Multicarrier Systems Design
TL;DR: It will be shown that the raised-cosine wavelet transform, as an orthogonal wavelet, does not support the design of multicarrier application well like the existing well-known orthogona wavelets.
