Latest Patents

Among his latest patents, Lawrie has developed a "Circuit for forward error correction encoding of data blocks." This invention discloses approaches for encoding N symbols of a sequence in parallel using an R parity symbol encoding algorithm. The process involves adding a first symbol matrix to a first parity matrix over a finite field to produce a first intermediate matrix. This matrix is then multiplied by coefficient matrices to generate further intermediate matrices, ultimately leading to a revised parity matrix.

Another notable patent is the "Pipelined turbo convolution code decoder." In this embodiment, a method of block decoding is provided, where multiple decoding iterations are performed using a circular pipeline of processing stages. Each stage executes soft-input-soft-output (SISO) decoding operations on data blocks, enhancing the efficiency of the decoding process.
