7th International ITG Conference on Source and Channel Coding, 2008

A special class of fix-free codes called gamma-expandable fix-free codes is defined. An exact sufficient condition for the existence of a gamma-expandable D-ary fix-free code is derived. Using the concept of gamma-expandability we present some Kraft-type sufficient conditions for the existence of D-ary fix- free codes.

• Let q≥5 be a prime number. Let$k={\BBQ}(\sqrt{d})$be a quadratic number field, where$d = (-1)^{(q(q-1))/(2)}\bullet (-(q-1)^{q-1}uw^{q}+u^{2}q^{q})$. Then the class number of k is divisible by q for certain integers u, w. Conversely, assume Ω/k is an unramified cyclic extension of degree q(which implies the class number of k is divisible by q), and Ω is the splitting field of some irreducible trinomial f(X) = Xq-aX-b with integer coefficients,$k={\BBQ}(\sqrt{D(f)})$with D(f) the discriminant of f(X). Then f(X) must be of the form f(X= Xq-uq−2wX-uq−1in a certain sense where u, w are certain integers. Therefore,$k={\BBQ}(\sqrt{d})$with$d = (-1)^{(q(q-1))/(2)} (-(q-1)^{q-1}uw^{q}+u^{2}q^{q})$. Moreover, the above two results are both generalized for certain kinds of general polynomials.

• This paper is concerned with filtering of hidden Markov processes (HMP) which possess (or approximately possess) the property of lumpability. This property is a generalization of the property of lumpability of a Markov chain which has been previously addressed by others. In essence, the property of lumpability means that there is a partition of the (atomic) states of the Markov chain into aggregated sets which act in a similar manner as far as the state dynamics and observation statistics are concerned. We prove necessary and sufficient conditions on the HMP for exact lumpability to hold. For a particular class of hidden Markov models (HMM), namely finite output alphabet models, conditions for lumpability of all HMP representable by a specified HMM are given. The corresponding optimal filter algorithms for the aggregated states are then derived. The paper also describes an approach to efficient suboptimal filtering for HMP which are approximately lumpable. By this we mean that the HMM generating the process may be approximated by a lumpable HMM. This approach involves directly finding a lumped HMM which approximates the original HMM well, in a matrix norm sense. An alternative approach for model reduction based on approximating a given HMM by an exactly lumpable HMM is also derived. This method is based on the alternating convex projections algorithm. Some simulation examples are presented which illustrate the performance of the suboptimal filtering algorithms.
