  10. Simplified Common Experiment Scheme The wired set up is selected to measure the stable and accurate interference power so that the quantitative measurements are performed rather easily. General test flow PER or BER measurement ‘Minimum sensitivity’ is measured by desired signal only Victim Rx systems Victim Tx systems + ATT1 Set Desired signal to a certain level from ‘Minimum sensitivity’, Measure PER/BER By adding various level of Interference signals ATT2 ○ AWGN DS- UWB MB-OFDM IR (1M,10M) The output is C/N vs. BER (PER) Y.

  13. Reminder The following data are just sampled cases of various equipments that serve for Fixed Microwave radio systems, GPS, Cellular phones, Broadcasting, Mobile broadcasting, Fixed-satellite service, Wireless access, respectively. The mission of this Task Force is to perform the demonstration test and submit the data to the upper level council for the discussion of the acceptable UWB interference level. Therefore, the Task Group does not make any evaluation on UWB interference acceptance level. Y. Sanada (UWB Demonstration Experiments Task Force)

Sanada (UWB Demonstration Experiments Task Force)

  17. GPS GPS signal power is set to -130dBm. In the left figure, the power level is as is, in both DS and MB, due to too small output to set -75dBm/MHz (FCC Mask). The right figure is set to -75dBm/MHz by removing IR BPF. The X-axis value is from -75dBm/MHz. For example, 45dB means -(75 + 45) = - 120dBm/MHz equivalent. Y. Sanada (UWB Demonstration Experiments Task Force)

  18. Cellular Phones (1) PDC (3) 1xEV-DO (2) WCDMA Y. Sanada (UWB Demonstration Experiments Task Force)

  19. Cellular Phones • Power measurements • The cellular receiver frequencies are located at the out of band of DS-UWB and MB-OFDM. Therefore, these powers are not measured and it means their power at that frequency is under the SA measurement limit of • -153dBm/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. Y. Sanada (UWB Demonstration Experiments Task Force)

Analog FPU’s DUs are the value observed when FPU receiver power is set to -59.9dBm. Also the Analog FPU’s value is by hearing evaluation. ＊AWGN in analog FPU test utilizes the BPF of BW 40MHz. Y.

  26. Mobile Broadcasting These results are obtained under the condition of the specific single UWB signal sources. Therefore it can NOT be said that the results obtained here are applicable to other UWB signals and/or its operation under the different conditions from specified here. Y. Sanada (UWB Demonstration Experiments Task Force)

  27. Fixed-Satellite Service Experiment Conditions *UWB-A/B/C/D corresponds to one of DS-UWB, MB-OFDM, IR-UWB(PRF 1MHz) or IR-UWB(PRF 10MHz), but not specified in this document. Y. Sanada (UWB Demonstration Experiments Task Force)

  30. Fixed-Satellite Service Y. Sanada (UWB Demonstration Experiments Task Force)

  31. 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 575MHz, the FSS should be considered as a wideband system.
