Technical Field

Background
Digital telephone systems have traditionally relied on standardized speech coding and decoding procedures with fixed sample rates to ensure compatibility between arbitrarily selected transmitter-receiver pairs. The development of second generation digital cellular networks and their functionally enhanced terminals has led to a situation where a complete one-to-one compatibility with respect to the sampling rate is not possible to guarantee, i.e. the speech encoder in the transmitting terminal may use an input sampling rate that is different from the output sampling rate of the speech decoder in the terminal. Linear prediction or LP analysis of the original speech signal may also be performed on a signal having a narrower frequency band than the actual input signal due to complexity constraints. An advanced speech decoder of a receiving terminal must be able to generate an LP filter with a bandwidth wider than that used in the analysis and to generate a wideband output signal from narrowband input parameters. The generation of wideband LP filters from existing narrowband information is also of wide applicability.
