WebThe power budget equation states that the power budget in a transmission system must equal the sum of all power losses plus the power margin. The power budget is the difference between the transmitter output power and the receiver sensitivity in dBm. The equation is thus PT −SR =ALF +LC +LA +M where • P T = transmitter output power (dBm) • S WebThe power would be lowered, say to -61 dBm, and the process repeated. At -90dBm suppose the BER was 1.9%. The power would then be dropped to -90.5 dBm, and suppose the BER was 2.03%. The resultant sensitivity of the receiver would be recorded as -90 dBm, because this is the lowest power at which reliable communication was measured. shirt manufacturing process pdf

In general, it is clear that for a receiver to "see" a signal it has to be greater than the noise floor. To actually detect the signal, however, it is often required to be at a power level greater than the noise floor by an amount that is dependent on the type of detection used as well as other factors. There are exceptions to this requirement but coverage of these cases is outside the scope of this article.
