Aspects of the disclosure provide a method and device performing input bit allocation that includes receiving broadcasting information bits, generating timing related bits for the broadcasting information bits, and selecting a portion of the generated timing related bits. The method and device can further include allocating each of the selected timing related bits to selected input bits of an encoder, so that each of the selected timing related bits is allocated to an input bit of the encoder corresponding to an available bit channel of the encoder where the selected inputs bits of the encoder correspond to encoded bits that are located in a front portion of the encoded bits.

Polar bit allocation for partial content extraction

The authors describe a synchronization method for short length words that uses message dependent synchronization digits. To each message to be transmitted, redundant digits at the encoder side are assigned. The redundant digits depend on two neighbor messages and are chosen so that at the decoder side maximum separation can be detected between the synchronized and unsynchronized modes. They analyze the decoding performance for transmission over an AWGN (additive white Gaussian noise) channel with synchronization transition errors. If the length of the messages is taken as equal to 8, then the method can be used to achieve symbol synchronization for length-255 Reed-Solomon codes. Simulation results are given for hard as well as soft decision decoding. >
