Certainly, all the exacting, pared-down takes on traditional music here – country, bluegrass, Dylan – speak of artists distilling their influences until the most spartan and flab-free iteration results.
Therefore, it is more desirable to find a CDIsp probing scheme free of iteration for the multi-antenna CR system.
The proposed CDIsp probing scheme has a closed-form solution and is free of iteration between the probing and acquisition, which is desirable in CR system. 2.
The CDIsp probing scheme by exploiting the hidden feedback in primary system has been proposed, with a solution free of iteration and of low complexity.
Firstly, a model-free policy iteration algorithm is derived and its convergence is proved.
The algebraic solver consists of a pre-conditioned transpose-free Krylov iteration for the conservation equations and optimized multigrid algorithms for solving the Poisson equation for the gravitational potential and the transport-diffusion equation for the radiation density in flow regions with dynamically varying optical depths.
The constructed algorithm turns out to be completely iteration free.
The first few packets were decoded error free for the 1st iteration itself without employing adaptive Doppler correction.
The effectiveness of various combinations of these preconditioners are compared using the source iteration, matrix-free Picard Krylov, and nonlinear Krylov acceleration methods.
For solving highly nonlinear characteristic curves, we propose an iteration-free L-stable method equipped with an error correction technique and a classical collocation method.
Analogous to [7], the global pulse replacement (GPR) [8], adopted by G.729.1 [9], and the iteration-free pulse replacement (IFPR) [10],[11] methods are proposed to further efficiently reduce the search complexity.
