The potential for capacity increase in multiantenna wireless communication systems has drawn considerable attention to space-time codes. However, most of the existing space-time code construction methods have assumed ideal channel models: either quasi-static fading or fast fading. In this work, we derive the performance criteria for space-time coded wireless communication systems taking into ac...

To realize the in-motion alignment of strapdown inertial navigation system (SINS) under geographic latitude uncertainty, we propose a estimation and method based on integral dynamic window polynomial fitting (IDW-PF) improved Kalman filter (IKF). First, (IDW) is designed to smooth out high-frequency line motion interference accelerometer noise. Second, specific force performed for cubic (PF) wi...

ABSTRACT The Advanced LIGO and Virgo gravitational-wave observatories have opened a new window with which to study the inspiral mergers of binary compact objects. These observations are most powerful when coordinated multimessenger observations. This was underlined by first observation neutron star merger GW170817, coincident short gamma-ray burst, GRB170817A, identification host galaxy NGC 499...

0.1 Proofs of Theorems 4.1, 4.2 & 5.2 Proof of Theorem 4.1: Let bn = pn+ln, where pn = b √ nc. Define a block of observations as Bn(i) = i + bn(0, 1], i ∈ Z. We first divide Rn into non-overlapped blocks of observations. Let Kn = {k ∈ Z : Bn(bnk) ⊂ Rn} represents the index set of all complete blocks Bn(bnk) = bn(k + (0, 1]) lying inside Rn. For each k ∈ Kn, we further divide each block into lar...

Coded modulation (usually with interleaving) is used in fading channel cornmunications to achieve good error performance. The major benefit froin using coded modulation in fading channels is achieved if each code symbol of a codeword (or coded sequence) suffers statistically different fading (preferably independent fading). However, in many applications of mobile communications (e.g. in a metro...

This study compared conventional static fading, where the problem solving responsibility of the learner increases at a fixed sequence, with a novel adaptive fading design in which the learner assumes more problem solving responsibility only if her or his previous solution attempt is successful. This study was conducted in the engineering knowledge domain of introductory electrical circuit analy...
