Abstract
The inventive data decoding system provides 3/5 voting on data blocks (1 . . . 11) received in a frame. A counter circuit of the system counts the bits in the data blocks and raises a repeat flag (RFLAG) at the end of each data block. The RFLAG signal causes an interrupt in a controlling processor, enabling the processor to monitor and control the receiving synchronism. The inventive procedure can be used on Forward Control Channel (FOCC) and Forward Voice Channel (FVC) channels in the Total Access Communication System (TACS) or the Advanced Mobile Phone Services (AMPS) mobile phone systems.
