    Abstract: A multi-part fixed codebook includes both individual fixed codebooks for each channel and a shared fixed codebook. Although the shared fixed codebook is common to all channels, the channels are associated with individual lags. Furthermore, the individual fixed codebooks are associated with individual gains, and the individual lags are also associated with individual gains. The excitation from each individual fixed codebook is added to the corresponding excitation (a shared codebook vector, but individual lags and gains for each channel) from the shared fixed codebook.

    Abstract: A method of coding a sampled speech signal vector in an analysis-by-synthesis coding procedure includes the step of forming an optimum excitation vector comprising a linear combination of a code vector from a fixed code book and a long term predictor vector. A first estimate of the long term predictor vector is formed in an open loop analysis. A second estimate of the-long term predictor vector is formed in a closed loop analysis. Finally, each of the first and second estimates are combined in an exhaustive search with each code vector of the fixed code book to form that excitation vector that gives the best coding of the speech signal vector.

    Abstract: A broadcast channel, such as a broadcast control channel that carries a short message service, in a GSM/EDGE or similar communication system can be extended with additional timeslots. These additional timeslots can be pointed out in a tree structure, the root of which is in the SMS broadcast channel. The extended broadcast channel can be used for broadcast-like services provided under a multimedia broadcast/multicast service.
