Study on the Emission Limits of UWB Based on the Entire Physical Layer Model Method

Influence of PCC for interferences mitigation from cognitive radio Ultra-Wideband

“…s lrJ"(J"-l) (8) As can be seen from (8), the power spectrum of the weighted subcarriers falls off as 1 I J4 which is faster than the case of OFDM.…”

“…Taking case of reference distance 1m and BER less than 1O-3 ,some simulation results about the electromagnetic compatibility between UWB and narrowband system have been achieved [8]. We can learn from the results that the emission power of UWB system must be less than -86dBm/MHz to avoid interfering with the GPS system.…”

On coexistence between UWB and OFDM-MIMO systems

“…Theoretical methodologies are easy to understand and apply; however, without enough information of both the UWB system and victim systems, the result is lack of accuracy and reliability. Reference [8] proposed another method to calculate the EIRP of UWB system based on physical layer model (PHYL-M) simulation. It has been proved that the result of PHYL-M method is much more accurate and reliable than that of INR criteria, since the whole characteristics of wireless systems are involved, and Monte-Carlo method is employed to guarantee the reliability of the results.…”
