A Simple Method to Estimate the Impact of Different Radiated Emission Limits on Digital Radio Receiver Performance
نویسنده
چکیده
A simple model to estimate the bit error probability (BEP) for a digital radio receiver, co-located with an undesired radiated interference source, is proposed. Co-location is defined as the area around the receiver (radius r), where an interferer has a significant impact on the BEP. The interference source is approximated to be of Gaussian type. A comparison of the emission limits given in Euronorm EN55022, Class A and B, and RE 102 in MIL-STD-461D on this radius r is presented. For Differential Phase-Shift Keying systems, assuming BEP <10, at SNR = 12 dB, the model delivers for Class A: r ≈ 70 m, for Class B: r ≈ 35 m and for RE102: r ≈ 10 m.

On Digital Radio Receiver Performance in Electromagnetic Interference Environments
adiated emission from electronic equipment, co-located to a digital radio receiver, can affect receiving performance. It is therefore of great importance that this undesired emission be considered in the early design phase of a system containing radio equipment. For this purpose, methods to estimate the performance degradation on digital radio receivers in such environment must be available. Fr...

متن کاملEstimating the Number of Wideband Radio Sources
In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...
