Latest Patents

Karczewski's latest patents include a method and apparatus for encoding and decoding error correction codes in communication devices. This invention involves a communication device that receives and decodes a codeword of predetermined length, which includes information and parity bits. The device comprises a memory for storing the codeword in segments, with each segment containing multiple bits forming bit combinations. A first look-up table stores parity vectors corresponding to these bit combinations, while a second look-up table stores values corresponding to syndrome vectors. The processing unit uses these segments to locate corresponding parity vectors and identify erroneous bits in the codeword.

Another significant patent is for automatic modulation calibration in a radio transmitter. This invention employs circuitry to automatically calibrate errors in a modulated carrier signal. A generator creates a low-frequency square wave for data, which is then used to generate a modulating signal. The modulated carrier signal is down-converted to an intermediate frequency signal, and the instantaneous signal level is compared to a steady state level to determine if adjustments are necessary.
