Column Listing

Column	Column Name	Element	Type	Dimension	Description
1	Time	Time	Real Number or Text	Date	Time.
2	g/T	g/T	Real Number	GainTempRatio	G/T = (Receiver Gain)/(System Temperature at the Receiver). The ratio of the receive antenna gain G to the total system temperature T is the "figure of merit" for the receiver (in dB/K). The figure of merit is independent of the point where it is calculated. However, the gain and system temperature must be specified at the same point.
3	Eb/No	Eb/No	Real Number	Ratio	The energy per bit to noise ratio (Eb/No) where Eb is the energy per bit and No = kT (Boltzmann's constant * system temperature).
4	BER	BER	Real Number	Unitless	Bit Error Rate (BER) is the probability that a bit is in error (i.e. a zero is transmitted but a one is received). The BER is the number of bits in error divided by the total number of bits sent. STK uses table lookup from a .mod file to extract a BER given an Eb/No. STK interpolates the table as necessary to determine the appropriate bit error rate for a particular bit energy level. If the bit energy is smaller than the first value in the table, the bit error rate for the first value is used. If the bit energy is larger than the last value in the table, a default bit error rate of 1.0e-30 is used to indicate no errors.
