    A decoding method for binary two-error correcting cyclic codes whose generator polynomials have at most two irreducible factors is presented. This class includes binary narrow-sense BCH codes with designed distance 5. The decoding algorithm uses the Zech logarithm for the finite field in which the roots of the code lie View full abstract»

    A token-ring local area network (LAN) with an infinite number of nodes uniformly distributed around the ring is considered. A token that circulates around the ring at a constant speed stops to serve fixed length packets that are generated by the nodes. It is assumed that the cumulative arrival process of packets constitutes a two-dimensional Poisson process. Given a fixed point on the ring, called... View full abstract»

    A series of algorithms, circuit designs, and analytical techniques as well as a few tricks are presented. Each is essential to the design, which created a constraint-length-15, 1-Mb/s Viterbi decoder. The focus is the maximum-likelihood decoding of very-long-constraint-length convolutional codes, but many of the concepts will find other applications ranging from extremely fast constraint-length-7 ...

  • Optimization of offset for OQPSK with time limited pulses

    The optimum offset for offset quaternary phase shift keying (OQPSK) in the presence of carrier phase error is determined for some time limited pulse shapes. It is shown that, for certain pulse shapes, T/2 is optimum in a minimum probability of error sense. In the case of bipolar pulse shaping it is seen that T/2 is not the optimum. It is shown that OQPSK with shaped pulses may be... View full abstract»

  • Error performance of interleaved trellis-coded PSK modulations in correlated Rayleigh fading channels

    The authors derive an exact and easily computed expression for the pairwise error event probability of interleaved coded PSK modulations transmitted over channels with correlated Rayleigh flat fading and additive white Gaussian noise. Both coherent and differential detection are considered. In the case of coded DPSK, it is found that full interleaving does not necessarily provide the best error pe... View full abstract»
