Fig. 11From: Experimental evaluation of interference alignment for broadband WLAN systemsEstimated PDF of the SRNR of the desired and interfering links at each receiver. The SRNR is estimated during the training stage according to the formulas given in Table 1. More specifically, the SRNR is computed for each subcarrier index and averaged over all OFDM symbols in a given frame. Finally, the PDF is estimated from the obtained set of SRNR valuesBack to article page
