He has made significant contributions to the field of digital signal processing, particularly in error correction methods for digital signals. With a total of 3 patents to his name, Nilesh continues to push the boundaries of innovation in technology.
Latest Patents
One of Nilesh's latest patents focuses on "Parity error correction for band-limited digital signals." This innovative error correction method addresses the challenge of correcting and replacing erroneous digital signal samples in a receiver. The method begins by ascertaining through a parity check whether a sample is erroneous. It then selects M most significant bits (MSBs), where M is less than or equal to N, and generates M test samples. Each test sample is created by inverting a single bit from the M bits while keeping the other bits unchanged. These test samples are expanded and passed through a selected low pass filter, such as a 15 kHz filter, to obtain a filtered output. A differential value is calculated between the test sample and its filtered output, and the test sample that produces the least differential value is chosen to replace the erroneous signal sample. This technique is particularly applicable in NICAM demodulators that receive 14-bit sample signals at 32 kHz, which are companded to 10 bits, from which 6 MSB parity encoded bits are selected for producing test samples.
