METHOD AND ENCODER FOR ENCODING A PLURALITY OF INPUT SIGNALS TO GENERATE CORRESPONDING CODE DATA, METHOD AND DECODER FOR DECODING CODED SIGNALS, ENTRY OF SIGNALS 1, r) for generating encoded data (100) is provided. The method involves processing the input signals (1, r) to determine first parameters (sym ~ 1 ~, sym ~ 2 ~) describing relative phase difference and time difference between signals (1, r), and apply these first parameters (sym ~ 1 ~, sym ~ 2 ~) to process input signals to generate intermediate signals. The method involves processing the intermediate signals to determine second parameters (≤; IID, p) describing angular rotation of the first intermediate signals to generate a dominant signal (m) and a residual signal (2), the dominant signal (m) having a magnitude or energy greater than that of the residual signal (s). These second parameters are applicable for processing the intermediate signals to generate the dominant (m) and residual (s) signals. The method also involves quantizing the first parameters, the second parameters, and dominant and residual signals (m, s) to generate corresponding quantized data for subsequent multiplexing to generate the encoded data (100).
