The device automatically interference cancellation based on the algorithm of Gram-Schmidt HIGH PERFORMANCE COMPUTING

摘要

The utility model automatic compensation system interference based on the Gram-Schmidt algorithm with high computational efficiency relates to the field of radar. Technical result of utility model is to reduce the total amount of computation. The technical result is achieved due to the input conversion unit and use the weighting coefficients compensation unit with increased computational efficiency. The apparatus comprises a switching keys in the number of reception channels, connected in series with the weighting coefficient calculating unit and the unit conversion weight coefficients, and the compensation unit. Switching keys in step estimates the weighting coefficients supplied digital signals of the reception channels at weighting coefficient calculating unit, and at step compensation unit to compensate. Weighting coefficient calculating unit calculates the weight matrix on a modified Gram-Schmidt algorithm. conversion unit converts a matrix of weighting coefficients in weighting coefficient weight vector. compensation unit performs the operation of receiving channels weighted summation signals.
