Abstract

DC60 (11/02/45) A method is proposed for the encoding modulation of digital data where the user bit is divided into wires. Parallel signal And user bits are encoded - channels at different encoding rates depending on the sensitivity of Its mistake The user bits, which are encrypted - different channels, are then stirred separately in time. In this case, different encoding rates are used and each number per transmission frame of the encrypted user bit - channels at different encoding rates. Signaled to the receiver So the receiver can Performs decrambling and channel decoding. A method is proposed for an encrypted modulation of digital data that the user bits are divided into strings. Parallel signal And user bits are encoded - channels at different encoding rates depending on the sensitivity of Its mistake The user bits, which are encrypted - different channels, are then stirred separately in time. In this case, different encoding rates are used and each number per transmission frame of the encrypted user bit - channels at different encoding rates. Signaled to the receiver So the receiver can Performs decrambling and channel decoding.
