Adaptive digital beamformer coefficient processor for satellite signal interference reduction

A method for computing filter coefficients of a beamformer based on a segment of input samples comprising the steps of:

• dividing the segment of input samples into a plurality of blocks of input samples;
• receiving the plurality of blocks of input samples in a shared memory;
• reading the plurality of blocks of input samples by a plurality of partial covariance processors from the shared memory wherein each of the plurality of partial covariance processors compute a partial covariance matrix for each block of input samples read by the partial covariance processor;
• adding the plurality of partial covariance matrices.

An apparatus for computing filter coefficients of a beamformer based on a segment of input samples wherein the segment of input samples are divided into a plurality of blocks of input samples, the apparatus comprising:

• a shared memory for receiving the plurality of blocks of input samples at a first rate wherein a first block of the plurality of blocks is received in a shared memory at a first time;
• and
• a processor for reading the plurality of blocks of input samples from the shared memory at a second rate, computing a plurality of partial covariance matrices for the plurality of blocks read from the shared memory, adding the plurality of partial covariance matrices,
• wherein the first block of the plurality of blocks is read from the shared memory at a second time, wherein the second time is delayed from the first time and the second rate is greater than the first rate.
