Figure 8From: On the performance of MIMO RFID backscattering channelsThe BER performance comparison between Alamouti’s coding scheme and identical signaling scheme. A significant BER improvement by Alamouti’s code is observed for N = 1, while the improvement is much smaller when N ≥ 2. These properties can be explained by our analysis of the MIMO RFID channel under the OSTBC and identical signaling schemes.Back to article page
