NettetThe link margin is the amount that the received signal power exceeds the receiver sensitivity. M = P R − S. where M is link margin (in decibels), P R is signal strength at the receiver system input (dBm), and S is receiver system sensitivity at output of receiving antenna, including the effects of any cable losses from the antenna (dBm). NettetFinally, the System Link Margin (SLM) was calculated based on a Bit Error Rate (BER) of 0.0001. Finally, using the information described above, summary tables were generated for each ground station location, for 0.1% outage probability, a max BER of 0.0001 at various Bit Rates were generated. martino silviaNettetExample 4-5: Link Budget Analysis of an 802.11b System The occupied bandwidth of an 802.11(b) spread spectrum system is 22 MHz.Each bit is spread over 11 chips.
