1. A system for processing an AMR signaling frame to be transmitted on a GERAN half rate channel utilizing a modulation scheme carrying n bits (n>

  • /=2) in one symbol, the system comprising;

    coder part (300), compatible with coder defined for a GSM half rate channel utilizing a GMSK modulation scheme, said coder part being adapted to output a coded bit stream,repeater (309), responsive to the coder part, for repeating each bit of the coded bit stream n times, whereby a repeated bit stream is obtained, andsymbol former (310), responsive to said repeater, for forming symbols to be transmitted from said repeated bit stream.
