% Computes communications sytems data rates from gains
Computes channel data rate from transmission and receiver gains. Need 22
Mbps for 1080p HDTV. Type DataRateFromGain for a demo.
--------------------------------------------------------------------------
Form:
[dR,pR] = DataRateFromGain( power, d )
--------------------------------------------------------------------------
------
Inputs
------
power (1,:) Power transmit (W)
d (.) Data structure
.fGHz (1,1) Frequency (GHz)
.range (1,1) Range (km)
.gainTransmit (1,1) Transmission gain
.gainReceive (1,1) Receiver gain
.tempS (1,1) Receiver noise temperature (deg-K)
.modulation (1,:) 'BPSK' 'QPSK' 'DE-BPSK' 'DE-QPSK' 'D-BPSK'
.sN (1,1) Signal to noise ratio
-------
Outputs
-------
dR (1,:) Data rate (bps)
pR (1,:) Power received (W)
