| 20080310532 | Method for Signal Reception - In an OFDM mobile communications system, an algorithm for forming a preliminary estimate of the channel on pilot subcarriers is carried out. Based on this preliminary estimate, a channel property is estimated. This channel property is then used to decide whether to enter a mobile receiver mode or a stationary receiver mode. For example, in the mobile mode channel estimation is performed using only pilot symbols from the current symbol period, while in the static mode channel estimation is performed using pilot symbols from the current symbol period and pilot symbols from other symbol periods. | 12-18-2008 |
| 20090067519 | ESTIMATION OF LENGTH OF CHANNEL IMPULSE RESPONSE - In a receiver for processing OFDM encoded signals, wherein the OFDM encoded digital signals are transmitted by means of a symbol in each of subcarrier frequency channels, with at least some of said subcarriers containing user data symbols, an initial estimate of a channel frequency response is formed from magnitudes of user data symbols received in those subcarriers. Then, a correlation function of a channel impulse response is estimated by performing an inverse Fourier transform on the initial estimate of the channel frequency response, and the length of the channel impulse response is estimated by examining peaks in the estimated correlation function of the channel impulse response. | 03-12-2009 |
| 20100034302 | METHOD OF SYNCHRONIZING MULTI-CARRIER SYSTEMS AND MULTI-CARRIER SYSTEM - A method of synchronizing multi-carrier systems is provided, wherein the method comprises inserting a predefined frequency domain signal into a signal on a transmitter side of a multi-carrier system and multi-carrier modulating the signal. Furthermore, the method comprises transmitting the multi-carrier modulated signal via a carrier channel to a receiving side of the multi-carrier system, and synchronizing the multi-carrier modulated signal by using the predefined frequency domain signal portion of the multi-carrier modulated signal. | 02-11-2010 |
| 20100142634 | PILOT ALLOCATION IN SINGLE FREQUENCY NETWORK - The present invention relates to a distributed pilot scheme especially suited for single frequency networks used, for instance, for broadcasting digital TV. In current digital TV standards, e.g. DVB-T, the transmitters in the SFN transmit the exact same signal in the same frequency and at the same time. As a consequence the channel seen by the receiver is the channel created by the SFN characterized by a very long delay spread, which can be challenging to estimate. According to the present invention different, preferably orthogonal, pilot sequences are assigned to different transmitters in the same SFN so that the receiver can estimate the propagation channels from each transmitter to itself independently. | 06-10-2010 |

| 20110206137 | WATERMARKED BASED PHYSICAL LAYER AUTHENTICATION METHOD OF TRANSMITTERS IN OFD COMMUNICATIONS SYSTEMS - DVB-T2 is the next generation standard for the terrestrial digital broadcast. There is the request of identifying the transmitters in the Single Frequency Networks mainly for testing purposes. This might be achieved by embedding a watermark sequence in the transmitters to identify them uniquely. However, the transmitters can also be deployed in SFN so they have to transmit exactly the same data. Therefore, the watermark has to be added at the radio signal. It connot be added at content level as it happens in other standard as, for instance, in cellular systems. The invention proposes two possible new methods to watermark the transmitter ID in the DVB-T2 signal. In both cases we assign orthogonal pilot sequences to different transmitters. In one case the sequences are added at very low power to ensure no loss in the data rate. This is a very attractive alternative, but it might require a much more expensive receiver. In the second case the sequences are added in a specific set of sub-carriers reserved for this specific use. This requires a better receiver synchronization and it also generates a small loss in data rate, but ensure a very simple and robust way to provide the transmitter identification. | 08-25-2011 |

| 20090216852 | SYSTEM AND METHOD FOR UPDATING A DYNAMIC DOMAIN NAME SERVER - A system and method for synchronizing a dynamic domain name system (DDNS). Updated domain name information is received at a first datastore and sent to a second datastore. Updated domain name information is also received at the second datastore and sent to the first datastore. Either datastore determines whether the other datastore is available to receive the updated domain name information. If the receiving datastore is not available, the sending datastore waits until the receiving datastore is available. The first datastore is connected to a first master DNS server and the second datastore is connected to a second master DNS server. The first and second master servers share an IP address. When a request for domain name information is received at a router, the request is sent to a master DNS server selected from the first and second master DNS servers using the shared IP address. A master DNS server is selected to respond to the DNS request only if that master server is able to respond to the request. The requested domain name information is retrieved from the datastore connected to the selected DNS server and a response to the request for domain name information is generated. | 08-27-2009 |
