Patent EP-0336658-A2 (EP)
Inventor: THOMSON DAVID L
IPC: G10L13/00
Filed: 1989-03-31
Abstract: A harmonic speech coding arrangement where vector quantization is used to improve speech quality. Parameters are determined at the analyzer (120) of an illustrative coding arrangement to model the magnitude and phase spectra of the input speech. A first codebook of vectors is searched for a vector that closely approximates the difference between the true and estimated magnitude spectra. A second codebook of vectors is searched for a vector that closely approximates the difference between the true and the estimated phase spectra. Indices and scaling factors for the vectors are communicated to the synthesizer (160) such that scaled vectors can be added into the magnitude and phase spectra for use at the synthesizer in generating speech as a sum of sinusoids.

Abstract: Telecommunications apparatus is provided for use in the cordless telephone environment where a number of handsets are arranged to communicate with a plurality of base stations. 
     When a handset indicates that it wants to communicate with a base station it may be recognised by a base station which is not necessarily the nearest one for best reception. 
     The base station, before setting up a link, compares the received signal strength with a predetermined stored threshold level. If the signal strength is above the level, the base station immediately attempts to set up a link. If it is below the level, the identity of the handset is stored and if the same base station receives a subsequent request from the same handset it then attempts to set up a link with that handset.

Abstract: A fuzzy inference system which has both a fuzzy inference processing device (the fuzzy inference unit) and a calculation processing device. The linguistic values in the antecedent or consequent described in the inference rule, the real numerical values in the consequent, and the values of the variables set in the calculating and computing schemes are essential to processing and are generally contained in the fuzzy inference knowledge. If these values are not present in the fuzzy inference knowledge stored in the fuzzy inference device, that device transmits to the calculation processing device the information needed to calculate them. The calculation processing device executes the calculation processing. It then sends the results of the calculations back to the fuzzy inference device, which will then continue performing the fuzzy inference.
