摘要： A technique is disclosed, according to which it is possible to efficiently use network resources, to reduce the burden on a control device, and to control the communication between radio terminals by the control device when a transmitting side radio terminal and a receiving side radio terminal are connected to the same radio relay device. According to this technique, when a transmitting side UE1 and a receiving side UE2 are connected to the same E-Node B 103, the transmitting side UE1 divides a transmission packet addressed to UE2 into a first packet to be transmitted via a route not passing through ACGW 105 and a second packet to be transmitted via a route passing through ACGW 105, and the packets are transmitted to E-Node B 103. E-Node B 103 transmits the first packet to UE2 and also transmits the second packet to ACGW 105.

摘要： A scalable decoding apparatus capable of providing decoded audio signals of high quality having less degradation of a high frequency spectrum even when decoding audio signals by generating the high frequency spectrum by use of a low frequency spectrum. In the apparatus, an amplitude adjusting part uses different adjustment coefficients in accordance with the characteristic of first layer spectrum information to adjust the amplitude of a first layer decoded signal spectrum, and then outputs the amplitude-adjusted first layer decoded signal spectrum to a pseudo-spectrum generating part. Using amplitude-adjusted first layer decoded signal spectrum received from the amplitude adjusting part, the pseudo-spectrum generating part generates and outputs a pseudo-spectrum of high frequencies to a scaling part. The scaling part scales the spectrum received from the pseudo-spectrum generating part and then outputs it to an adder.

The device includes a power/correlation calculating unit (201), an intermediate value calculating unit (202), a codebook (203), a searching unit (204), and a decoding unit (205). The power/correlation calculating unit (201) determines the value of the correlation between an L signal and an M signal and the value of the correlation between an R signal and the M signal and calculates the power of the M signal. The intermediate value calculating unit (202) determines two intermediate values by using the power of the M signal and the values of the correlations. The codebook (203) holds scalar values. The searching unit (204) selects a coefficient for balance adjustment of the amplitude of the M signal with respect to the L signal from among the scalar values according to the two intermediate values. The decoding unit (205) determines the coefficient for balance adjustment of the M signal with respect to the R signal by using the selected coefficient for balance adjustment of the M signal with respect to the L signal on the basis of the quantitative relation between the amplitudes of the signals of when the M signal is generated by down-mixing the L and R signals.

摘要： A scalable encoding device for realizing scalable encoding by CELP encoding of a stereo sound signal and improving the encoding efficiency. In this device, an adder and a multiplier obtain an average of a first channel signal CH1 and a second channel signal CH2 as a monaural signal M. A CELP encoder for a monaural signal subjects the monaural signal M to CELP encoding, outputs the obtained encoded parameter to outside, and outputs a synthesized monaural signal M′ synthesized by using the encoded parameter to a first channel signal encoder. By using the synthesized monaural signal M′ and the second channel signal CH2, the first channel signal encoder subjects the first channel signal CH1 to CELP encoding to minimize the sum of the encoding distortion of the first channel signal CH1 and the encoding distortion of the second channel signal CH2.

摘要： There is provided a scalable decoding device capable of improving resistance against a transmission error. In the device, a narrow band LSP decoding unit (108) decodes narrow band LSP encoded information corresponding to a core layer of the current encoded information. A storage unit (126) stores a wide band quantized LSP corresponding to an extended layer of the past encoded information as a stored wide band LSP. When the wide band LSP encoded information is lost from the current encoded information, a compensation unit formed by a combination of a frame loss compensation unit (124) and a switching unit (128) generates a compensated wide band LSP by weighted addition of the band conversion LSP of the narrow band quantized LSP and the stored wide band LSP, thereby compensating the decoding signal of the lost wide band LSP encoded information by the compensated wide band LSP.

摘要： An encoder, decoder, encoding method, and decoding method enabling acquisition of high-quality decoded signal in scalable encoding of an original signal in first and second layers even if the second or upper layer section performs low bit-rate encoding. In the encoder, a spectrum residue shape codebook stores candidates of spectrum residue shape vectors, a spectrum residue gain codebook stores candidates of spectrum residue gains, and a spectrum residue shape vector and a spectrum residue gain are sequentially outputted from the candidates according to the instruction from a search section. A multiplier multiplies a candidate of the spectrum residue shape vector by a candidate of the spectrum residue gain and outputs the result to a filtering section. The filtering section performs filtering by using a pitch filter internal state set by a filter state setting section, a lag T outputted by a lag setting section, and a spectrum residue shape vector which has undergone gain adjustment.

摘要： Provided is a parameter decoding device which performs parameter compensation process so as to suppress degradation of a main observation quality in a prediction quantization. The parameter decoding device includes amplifiers (305-1 to 305-M) which multiply inputted quantization prediction residual vectors xn−1 to xn-M by a weighting coefficient β1 to βM. The amplifier (306) multiplies the preceding frame decoding LSF vector yn−1 by the weighting coefficients β−1. The amplifier (307) multiplies the code vector xn+1 outputted from a codebook (301) by the weighting coefficients β0. An adder (308) calculates the total of the vectors outputted from the amplifiers (305-1 to 305-M), the amplifier (306), and the amplifier (307). A selector switch (309) selects the vector outputted from the adder (308) if the frame erasure coding Bn of the current frame indicates that ‘the n-th frame is an erased frame’ and the frame erasure coding Bn+1 of the next frame indicates that ‘the n+1-th frame is a normal frame’.
