Latest Patents
Friedberg holds a patent for "Adaptive decision regions and metrics." This invention presents an improved decoding technique that is beneficial for hard decision decoding, such as quadrature phase shift keying (PSK) and quadrature amplitude modulation (QAM). It also enhances soft-decision techniques, including Viterbi decoding and trellis decoding. The system optimizes decision boundaries and reference constellations to minimize the bit error rate (BER). By adaptively adjusting these parameters based on the locations of received constellation points, the invention significantly improves BER without the need for nonlinear predistortion at the transmitter. This reduction in complexity and weight is particularly advantageous for applications like satellite communication systems.
