A transmission packet is formed by combining the sparse vectors with a selected set of sparse vectors representing past measurements and the incoming velocity of the sensor signals. A receiver decompresses the transmission packet by reconstructing, at a sparse recovery sub-layer of a receiver MAC layer, the encoded, modulated sensor signals. A decoder path removes the CSS modulation and Gray indexing, and Hamming decodes the sensors signals. |

Implementation of invertible functions using party logic
Parity logic is widely used in forward error correction codes and error detection codes. When used for error correction and error detection applications, the role of parity bits is to increase code distance by introducing memory between encoded bits and input bits at cost of overhead bits. Present disclosure provide systems and methods for implementing invertible parity functions using parity logic wherein ‘k’ input bits are received and encoded using a first invertible parity function. The ‘k’ input bits can be iteratively encoded to obtain nonlinearity and higher dependency between set of encoded parity bits and the ‘k’ input bits or other data bits. Further the decoding is performed on the set of encoded bits to retrieve original ‘k’ input bits using a second invertible parity function. |
