Abstract:
A method of lattice-quantizing an eight-long data point in a manner that minimizes storage requirements and computational complexity, comprising the steps of:a) acquiring the eight-long data point;b) multiplying each coordinate of the data point by the square root of two to form an inflated data point;c) rounding each coordinate of the inflated data point to the nearest integer;d) reducing modulo-two each coordinate of the rounded inflated data point to form an initial codeword;e) multiplying a parity-check matrix of an eight-bit Extending Hamming Code by the result of step (d) in the form of a column matrix to form a syndrome;f) correcting any single-bit error, if any, in the initial codeword;g) correcting any double-bit errors, if any, in the initial codeword;h) creating a signal packet if the initial codeword does not contain any single-bit and any double-bit errors; andi) transmitting the signal packet to a receiver.
