    A TEM lens antenna is described that provides the capability of generating 61 low-sidelobe dual-polarized beams over a 17° field of view, at both 4 and 6 GHz. Isolation between these beams is examined, and it is concluded that 6 of the available 61 beams may be used simultaneously in many different positions, while maintaining at least 27 dB isolation, for a total of 12 times frequency reuse.

    This paper identifies the improvements due to large-scale integration [LSI] in the areas of cost, performance, size, reliability, and testing of data communication equipments. An example using Motorola's MC6860 Digital Modem is given. Techniques for implementing linear functions using digital designs and processing methods are discussed along with future technology trends and projections. View full abstract»

    The growth of the communication industry has resulted in ever-increasing demands on the radio spectrum. This, in turn, has spurred the exploitation of previously unused frequency bands and the development of techniques for making better use of those already available. In this paper, spectral utilization is examined using the information-theory techniques of Shannon. The power-bandwidth tradeoff fo... View full abstract»
