Experimental study of wide area SIMO for ionospheric HF radio links

We propose a wide area cooperative communication scheme for ionospheric HF links in order to increase communication reliability and throughput under a given range and power. By exploiting multiple radios in a collaborative fashion, we can obtain diversity gains similar to Single Input Multiple Output (SIMO). Based on experimental results, this paper demonstrates the benefits of wide area cooperative communication strategies, and gives correlation function of diversity channels with different distance by measuring channel parameters.
