1. An apparatus in a mobile phone comprising:

  • a counter circuit to count a plurality of received data blocks contained in a frame;

    a 3/5-voting logic element operating on five of the plurality of received data blocks, wherein the 3/5 voting logic element receives the plurality of received data blocks as a data flow when the 3/5 voting logic element is selected with a bit enable signal, the 3/5 voting logic element performing a 3/5 voting process, producing a voting result and an output data stream at the end of the 3/5 voting process;

    a BCH decoding circuit having an input and output, the input being connected to the voting result and the output being a received data frame syndrome;

    a correction device having an input and a first and second output, the input being connected to the received data frame syndrome, the first output being a decoding result and the second output being a bit correction signal;

    a data buffer having an output and a plurality of inputs, a first one of the plurality of inputs being connected to the output data stream of the 3/5 voting logic element and a second one of the plurality of inputs being connected to the bit correction signal, the data buffer producing at its output a data stream of corrected data; and

    a receiver timer connected to the BCH-decoding circuit, 3/5-voting logic element and data buffer, which produces timing information for the BCH-decoding circuit, the 3/5-voting logic element, and the data buffer.
