System and method for using a microlet-based modem |
August 5, 2008 |
| A modem architecture and applicable method use microlet transforms to encode and exchange data or information. An encoder determines the probability states of a quantum representation, and uses the states to represent data in lossless manner. A block of data is reduced to a smaller s |
