Abstract
A coherent phase detector using a frequency discriminator for reducing a frequency encoded signal to baseband, thereby avoiding the necessity of generating a coherent RF phase reference signal. A baseband processor is provided to compensate for error components arising in the frequency discriminator output. The baseband processor includes feedback loops for DC level correction and automatic gain correction. A novel scheme is also described for reducing the influence of interbit crosstalk on the operation of the baseband processor.
