System and method for linearizing microwave transmitters
摘要
<p>A system for determining predistortion coefficients for microwave transmitters comprising: a digital signal source; a predistorter for distorting said digital signal; and a transmitter for transmitting said distorted digital signal; characterised by comprising a receiver for receiving said transmitted signal and providing a demodulated signal; a delay device for delaying said digital signal; a comparison device for comparing said delayed digital signal with said demodulated signal to produce a signal indicative of the error between said two signals; and a calculation device for determining said predistortion coefficients on the basis of said error indicative signal.</p>
