Error correction code (ECC) processing has so far been performed on dedicated hardware for previous generations of mobile communication standards, to meet latency and bandwidth constraints. As the 5G mobile standard, and its associated channel coding algorithms, are now being specified, modern CPUs are progressing to the point where software channel decoders can viably be contemplated. A key aspect in reaching this transition point is to get the most of CPUs SIMD units on the decoding algorithms being pondered for 5G mobile standards. The nature and diversity of such algorithms requires highly versatile programming tools. This paper demonstrates the virtues and versatility of our MIPP SIMD wrapper in implementing a high performance portfolio of key ECC decoding algorithms.

In order to investigate the relationship and effect on the performance of magnetic modulator among applied DC current, excitation source, excitation loop current, sensitivity and induced voltage of detecting winding, this paper measured initial permeability, maximum permeability, saturation magnetic induction intensity, remanent magnetic induction intensity, coercivity, saturated magnetic field intensity, magnetization curve, permeability curve and hysteresis loop of main core 1J85 permalloy of magnetic modulator based on ballistic method. On this foundation, employ curve fitting tool of MATLAB; adopt multiple regression method to comprehensively compare and analyze the sum of squares due to error (SSE), coefficient of determination (R-square), degree-of-freedom adjusted coefficient of determination (Adjusted R-square), and root mean squared error (RMSE) of fitting results. Finally, establish B-H curve mathematical model based on the sum of arc-hyperbolic sine function and polynomial.
