    Abstract: Disclosed is a DC to DC converter (1). The DC to DC converter includes a first H-bridge converter circuit, a second H-bridge converter circuit sharing a phase leg with the first H-bridge converter circuit, a first rectifier circuit (12), a second rectifier circuit (14), a first transformer (11) and a second transformer (13). The primary winding of the first transformer is connected to the output terminals of the first H-bridge converter circuit, and the secondary winding of the first transformer is connected to the input terminals of the first rectifier circuit. The primary winding of the second transformer is connected to the output terminals of the second H-bridge converter circuit, and the secondary winding of the second transformer is connected to the input terminals of the second rectifier circuit. One of the output terminals of the first rectifier circuit and one of the output terminals of the second rectifier circuit are connected in series. The first rectifier circuit can compensate an insufficient part of the rated output power to provide the output power to a load. Since the first transformer and the second transformer commonly provide power to the load during a power transmitting period, transformers with smaller power level can be used to implement the first transformer and/or the second transformer, thereby the volume of the DC-DC converter being decreased.

    Abstract: The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate %2 and Rate 1/8, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate 1/8 VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate 1/8 voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate 1/8 voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.

    Abstract translation: 本发明涉及用于在CDMA 2000 1xEV-DV系统中在前向分组数据信道(F PDCH)上有效支持因特网协议上的语音(VoIP)的方法。 使用例如增强型可变速率编解码器(EVRC)编码VoIP中的主动语音,其分别对速率1,速率%2和速率1/8每20毫秒的语音产生171,80和16比特。 然而,在语音会话期间用户不活跃的时间大约60%,所以过多的系统带宽由速率1/8的VoIP数据包组成。 在本发明的一个实施例中,本发明的装置识别速率1/8语音帧分组并丢弃它们。 在本发明的另一个实施例中,本发明的装置识别速率1/8语音帧分组并选择它们中的一些用于进一步传输。 在这两个实施例中,信道利用率的效率都提高了,因为用于传输相对较少的信息(例如静音间隙)的信道带宽量减少了。

    Abstract: A method for adaptively adjusting power margin over a forward control channel PDCCH from a base station BS to a mobile station MS during a call. Corresponding message packets are sent in parallel over PDCCH and a data channel PDCH to an MS. The BS monitors a reverse channel ACKCH for an expected reply from the MS. If the reply is ACK, the power margin for the next subsequent transmission on PDCCH is lowered. If the reply is NACK, the power margin for the next subsequent transmission on PDCCH is lowered. If no reply is timely received, the power margin for the next subsequent transmission on PDCCH is raised. If the method is applied also to PDCH, an ACK reply causes the power margin on PDCH to decrease; a NACK reply causes the power margin on PDCH to increase, and no reply leaves the power margin on PDCH unchanged.
