摘要:
The present invention is directed to a system and method for reducing the need to perform signal clipping in a DMT transmitter. In accordance with one aspect of the invention, a method performs an inverse Fourier Transform on the input to produce a time-domain, digital value to be transmitted to a remote receiver. The method then evaluates the magnitude of the digital value to determine whether the magnitude exceeds a threshold value. Then, the method alters the input and re-performs an inverse Fourier Transform on the altered input, only if the step of evaluating the magnitude determines that the magnitude of the digital value exceeds the threshold value.

Disclosed is a system and method for signal conditioning and equalization in the time domain, preferably in a discrete multi-tone (DMT) modem. The system preferably includes a processor operating according to operating logic stored on a memory although a dedicated logical circuit may be employed. The operating logic includes logic executing the function of a low pass filter having a predetermined cutoff frequency configured to process a digitized data signal having a first sample rate f0, producing a filtered data signal at a second sample rate f1. The operating logic further includes logic which executes the function of a time domain equalizer, the time domain equalizer being configured to process the filtered signal to shorten the impulse response of the channel while at the same time, the time domain equalizer down-samples the filtered signal from the second sample rate f1, to a third sample rate f2 for further processing in the frequency domain.

Embodiments of the present disclosure encompasses virus-like particles, methods of making virus-like particles, including expression vectors, wherein the virus-like particles may comprise enhanced levels of capsid-bound a chimeric HN-Env polypeptide compared to VLPs derived from unmodified HIV-env polypeptides. Embodiments of the virus-like particle may have Env-specific epitopes exposed on the outer surface thereof. In one embodiment, the Env-specific epitopes exposed on the outer surface of the virus-like particle may specifically bind with an anti-HIV-Env specific antibody. Embodiments of the disclosure further includes methods of generating an antibody specific to an epitope of an HIV-Env polypeptide, comprising delivering to an animal or a human an effective amount of a suspension of virus-like particles comprising a chimeric HIV-Eny polypeptide, thereby inducing the formation of an antibody specific to an epitope of an HIV-1 eny polypeptide.

Provided is a method for transmitting 1x paging information through an HRPD network and responding to the 1x paging information by a dual-mode MS/AT. After the MS/AT turns to an HRPD network and informs an MSC of related information, if some 1x paging information arrives, the MSC sends a message indicating 1x service arrival to the PCF. An HRPD AN bears the 1x service arrival message that carries calling information sent from the PCF in the 1x service packet to send to the MS/AT. If the user, receiving the 1x service arrival message, chooses to accept a 1x call, the MS/AT terminates the service in the HRPD network and turns to the 1x network to send a “paging response” message to a 1x BS.

A method and device for authenticating a MS has an R-UIM by using CAVE Algorithm are provided. The hardware structure of the device includes a cdma2000/HRPD dual-mode chip, a User Identity Module supporting the CAVE algorithm. The dual-mode terminal forms the NAI value with the domain name stored in a memory of the dual-mode terminal in advance by the IMSI. The dual-mode terminal extracts a RAND that is necessary for the calculation of an authentication parameter1 from the Random values included in a Chap Challenge message, instructs the R-UIM card to use the CAVE algorithm to calculate the authentication parameter1 with the RAND and an existing SSD_A in the R-UIM card, and bears the authentication parameter1 by the Result domain of a Chap Response message. With the present invention, the wastes caused by the replacement of R-UIM cards can be avoided.

A method for Access Authentication in the High Rate Packet Data Network is proposed in the present invention comprising steps of the AN-AAA receiving the Radius Access Request message sent from the HRPD AN; the AN-AAA judging whether a terminal is a roaming one according to the Network Access ID and transmits the roaming terminal's authentication information to the terminal's home nerwork. If said terminal is a local one, the AN-AAA judges the type of the terminal according to the NAI value. If said terminal is a single-mode one, the AN-AAA works out the Result2 with the MD5 algorithm. if said terminal is in dual-mode, the AN-AAA calculates the Result2 with the CAVE algorithm to compare the Result1 with the Result2.
