Abstract: A coding method is adapted to select different codebook search algorithms according to varied types of input signals. An encoder using the coding method is also provided. As appropriate search algorithms may be selected according to all possible structural features of the input signals, certain types of signals for which satisfactory results may be obtained through simple computations may match with search algorithms suitable for these signal types and having low computation complexities, so as to achieve better performance with fewer system resources. Meanwhile, other types of signals that need complicated computations may be processed by more sophisticated search algorithms, thereby ensuring the coding quality.

Abstract: A method for quantizing vector. The method includes: performing a quantization process on a vector to be quantized by use of N basic codebook vectors and the adjustment vectors of each of the basic codebook vectors, generating a basic codebook vector and an adjustment vector used for quantizing the vectors to be quantized, N being a positive integer larger than or equal to 1. According to the present invention, based on the method a device for quantizing vector is disclosed. According to embodiments of the present invention, the quantization of an input vector is done by introducing the modification vectors for the base codebook vectors, therefore the memory amount of the base codebook vectors is reduced effectively, and the calculation amount is merely the calculation amount required for going through N codebooks. Therefore, the complexity of the vector quantization could be decreased effectively.

Abstract: A fixed codebook search method includes: initializing a counter; searching for pulses and calculating the value of a cost function Qk; initializing the counter if the Qk value increases; increasing the value of the counter if the Qk value does not increase; judging whether the value of the counter is greater than the threshold value; continuing the search process if the value of the counter is not greater than the threshold value; and ending the whole search process if the value of the counter is greater than the threshold value. The present invention reduces the search count and improves the search efficiency.

Abstract: The present invention relates to the field of communications, in particular, to a server for solving the problem related to the incompatibility between normal blades and multi-processing blades in a conventional server. The server according to an embodiment of the invention includes a backboard, on which backboard wiring and a first slot are disposed. At least two second slots are further disposed on the backboard. Both a first interface configured to be connected to a normal blade and a second interface configured to be connected to a multi-processing blade are disposed on each of the second slots, the first interface being connected to a corresponding Cluster Switch interface disposed on the first slot via the backboard wiring, and the second interface being interconnected directly via the backboard wiring or being connected to a corresponding Symmetrical Multi-Processing Switch interface disposed on the first slot via the backboard wiring.
