    A simple, parallel-mode tactile transducer for extracting three-dimensional digital representations of complex engineering components is proposed. In addition, algorithms for computer processing of the tactile information to produce a compact structural description of the scrutinized object are evolved. The possibility exists that these techniques might be applied to future generations of automati... View full abstract»

  • A probability diversity combiner for digital h.f. transmission

    The switched a posteriori probability (s.a.p.) diversity combiner has equivalent performance to maximum a posteriori probability (m.a.p.) combiner for dual diversity when binary transmission is used. Moreover, it is much simpler to implement since it is similar in principle to the conventional switched diversity combiner. The difference is that instead of switching to the branch with the highest s... View full abstract»

  • Detection processes for distorted binary signals

    The paper describes various iterative detection processes that are suitable for use in a synchronous serial data-transmission system, operating at a transmission rate of up to 10 000 bits per second over a slowly time varying channel. The methods of operation of the different detection processes are first described, and then the results of computer simulation tests are presented, comparing the tol... View full abstract»

    The error performance of filter threshold and integrate and dump demodulators is calculated, for phase shift key (p.s.k.) and fast frequency shift key (f.f.s.k) modulated data signals. A review is given of existing theory and techniques and some material is presented on f.f.s.k. demodulators. View full abstract»

  • Theoretical and practical investigation of error rates for digital f.m.

    Publication Year: 1976 , Page(s): 549 - 552
    Click to expandAbstract | PDF file iconPDF (452 KB)  

    The bounds for the probability of error for f.s.k. systems using optimum detection are stated. The upper bound is obtained for other cases of interest using non-optimum detection. The theoretical results are presented together with past practical results and some new practical results for a wide-band digital f.m. system. View full abstract»

  • Microwave holographic remote sensing using a Fourier transform/spherical scanning technique

    Publication Year: 1976 , Page(s): 555 - 559

    Spherical scanning is a very convenient means of mapping a microwave aperture for a localized remote imaging system. Provided that the scan angle does not exceed the derived limits for tolerable spherical aberration, a Fourier microwave hologram, recorded on a spherical surface, yields clearly identifiable, computer-reconstructed images.
