Therefore, these powers are not measured and it means their power at that frequency is under the SA measurement limit of -153 d. Bm/Hz. Interference Power at each desired signal strength point Next Table shows the comparison between AWGN and UWB at each desired signal strength points. The “path-loss” in Table means the total loss from Tx terminal to Rx terminal. The values shown are calculated from ATT set, system loss and receiver internal loss. Also “Signal group A” means the grouped data, where the power measurement was not done due to SA limit. The most outstanding “path-loss” is listed from the data of the group. Submission 19 Y.

Nov. 2005 Fixed-Satellite Service doc. : IEEE 802. 15 -15 -05 -0643 -01 -003 a Interference Source BER Performance White Noise Similar as the typical performance of the modem (CDM-550 T) tested UWB-A Depending on the data rate, the BER performance curves show 1 -1. 5 d. B difference. The maximum difference from the performance curve with the white noise is about 2 d. B. UWB-B Depending on the data rate, the BER performance curves show maximum 4 d. B difference. The maximum difference from the performance curve with the white noise is about 2 d. B. UWB-C Depending on the data rate, the BER performance curves show 0. 5 -1. 0 d. B difference. The maximum difference from the performance curve with the white noise is about 2 d. B. UWB-D The difference from the performance curve with the white noise is about 2 d. B. The limited number of measurement results are available due to synchronization loss. BER Performance: ・The BER performance as compared to that with the white noise depends on the data rate of the fixed-satellite service system. When the data rate is 2 Mbps, the BER performance is about 2 d. B worse than that with the AWGN. From the figures, more degradation can be observed as the data rate increases. ・When the white noise is used as the interference source, the BER performance does not change even if the data rate is changed. On the other hand, the BER performance changes depending on the data rate when the UWB signal source is employed as the interference (Maximum 4 d. B). Sync Loss Performance: Because the step of the attenuator is 1 d. B, the accurate measurement was not possible. From the figures, the sync loss point is almost same with the white noise with different data rates. However, there is at most 2 d. B difference with the UWB as the interference source.

doc. : IEEE 802. 15 -15 -05 -0643 -01 -003 a Nov. 2005 Fixed-Satellite Service Because the influence of the UWB signal sources is different from that of the white noise, additional experiments are required in order to obtain the detailed results. The additional experiments should be conducted with the following conditions; ・ Different combinations of the system parameters (modulation schemes, FEC parameters, etc. ) ・ Different signal levels ・ Receivers from different manufactures ・ With multiple UWB signal sources ・ Different frequencies offsets between UWB signals and FSS (as the UWB signal sources have ripples on their frequency spectrum) ・ More realistic transmission environments ・ As the bandwidth of the LNA is 575 MHz, the FSS should be considered as a wideband system.
