Supplementary Material

The proposed Tilted MIMO-THP in decentralized scenario.

The proposed power loading algorithm

Transmitted power vs. the number of Tilted angles in different block length N=5,10,20. (SNR=10dB, = nR =4, 4QAM). BER vs. SNR and several block length in MIMO-MMSE-THP with and without Power Loading (ρ=0.05). BER vs. SNR and several block length in MIMO-MMSE-THP with and without Power Loading (ρ=0.1).
