متن کاملMobile Digital Communications Using Phase Conjugating Arrays
A phase conjugation based method for full-duplex digital communications is discussed. The method uses a spatially confined and directive antenna pattern while a fullduplex digital communications link is maintained between moving platforms. The communications abilit~ of the array is based on processing the phase associated with the message and the phase associated with the platform’s motion sepa...
متن کاملA novel digital FM receiver for mobile and personal communications
Recently, a digital baseband receiver called zerointermediate frequency zero-crossing demodulator (ZIFZCD) was developed for digital FM signal detection. ZIFZCD is applicable to many worldwide mobile and personal communications systems. In addition, ZIFZCD offers lower power consumption and simpler implementation, compared to the conventional analog implementation [e.g., a limiter-discriminator...

متن کاملReduced State Viterbi Receivers for Digital Mobile Communications
In the context of the new North American TDMA standard for Digital Cellular, the problem we seek to address in this paper is the design of an adaptive detector and differential phase decoder. The technique used in the design is that of Maximum Likelihood Sequence Estimation, implemented by use of the Viterbi algorithm. Two solutions are proposed, the Shifted Viterbi Receiver and the Differentia...
