The information encoding apparatus (31) converts input text information to an intermediate code in accordance with a predetermined encoding method, and outputs a voice derived from voice information based on the intermediate code and supplemented with music arrangement information. The voice is transmitted either directly or via a broadcasting or communicating medium to a receiving side. The information decoding apparatus (34) on the receiving side receives the generated voice, recognizes a voice waveform from the received voice, and reproduces the original target information by decoding the intermediate code based on the recognized voice waveform.

Abstract: A Walsh code generator capable of performing signal processing at a high speed using the codewords of the Walsh code. A binary counter 3 generates a count signal counting upper (n-m) digits of a codeword number corresponding to a codeword of a Walsh code of plural bits. A parallel generation controller 4 generates, by the count signal and upper (n-m) bits of the codeword number, a parallel generation control signal for causing bits making up the codeword to be generated in parallel. A parallel Walsh code generator 5 generates the codeword in parallel by the parallel generation control signal and the lower m bits of the codeword number. The Walsh code generator may be reduced in the maximum operating frequency, while its power consumption may be lowered.

Abstract: While the phase of a PN code is being shifted every predetermined number of chips, correlation values with a received code are obtained. A plurality of the largest correlation values are selected from those that have been detected and designated to fingers. When a correlation value is obtained for each phase, the maximum value of the correlation values that have been detected is detected by a maximum value detecting circuit. The maximum value is stored in a maximum value memory. When a plurality of the largest correlation values are selected, the maximum value that has been stored in the maximum value memory is used.
