Abstract: Method for informing a mobile terminal (MN), which is located in a first cell, on system information of a second cell. In particular, pointers to the system information are transmitted from the base station of the first cell to the mobile node, while the mobile node is located in the first cell. The MN processes said pointer, comprising e.g. information on the transmission format and timing of system information in the second cell. Using an acquisition gap assigned by the network, the MN changes the frequency to the second frequency so as to acquire the system information based on the previously received scheduling information. Thus, the acquisition time for important system information may be reduced, as no Master Information Block on the second frequency has to be processed first, in order to acquire the system information.

Abstract: Disclosed is a stereo speech decoding device and others capable of reducing a stereo speech encoding bit rate and suppressing degradation of speech quality. In this device, a section 0 where only an L-channel signal SL(n) exists is identified, a monaural signal of the section 0 transmitted from the stereo speech encoding side is made to be an L-channel signal of section 0 SL(0)(n), and the L-channel signal SL(0)(n) of the section 0 is scale-adjusted so as to predict an R-channel signal SR(1)(n) of a section 1. A contribution of the R-channel signal SR(1)(n) of the predicted section 1 is subtracted from the monaural signal of the section 1 so as to isolate the L-channel signal SL(1)(n) of the section 1. This device continuously repeats the aforementioned scale adjustment and isolation process so as to obtain the L-channel signal SL(n) and the R-channel signal SR(n) of all the sections.

Abstract: In order to improve a transmission speed of multilevel light transmission, increasing the number of light emitting elements is effective. However, in a method in which light outputs from a plurality of light emitting elements are added, because common mode noise contained in the light outputs is added, deterioration in transmission quality caused by the common mode noise prominently arises. Therefore, a difference between two light outputs is previously assigned to data to be transmitted. Specifically, an optical transmitter 102 converts data Dt to multilevel optical signals OSm1 and OSm2 and transmits the converted multilevel optical signals to an optical receiver 103. The optical receiver 103 restores the data Dt which is previously assigned to a difference between electrical signals ESr1 and ESr2 converted from the multilevel optical signals OSm1 and OSm2.

When the received radio communication data is addressed to the local device, a communication/response information generation unit correlates the identifier to the reservation time slot, records them in a communication reservation table, and generates communication time reservation response information including information of the reservation time slot.

Accordingly, the opening of the current blocking layer is effectively narrowed, so as to realize a self-pulsation nitride semiconductor laser device.

Abstract: A mixer circuit of a receiving system, requiring low noise characteristics at lower frequency, includes a bypass current source (41) which is connected in parallel with an LO transistor (21) between an IF output terminal (33) and a drain terminal of an RF transistor (11), and a bypass current source (42) which is connected in parallel with an LO transistor (22) between an IF output terminal (34) and the drain terminal of the RF transistor (11), thereby decreasing a current flowing through the LO transistors (21, 22) without decreasing a bias current flowing through the RF transistor (11). Accordingly, it is possible to suppress flicker noises occurring from the LO transistors (21, 22) without lowering the gain of the mixer, thereby realizing a mixer circuit with excellent low frequency noise characteristics, which can improve the NF characteristics at lower frequency.
