| 20080205337 | Methods and Devices for Allocating Data in a Wireless Communication System - A system and method for identifying a resource region including a plurality of symbols, allocating pilot signals to the resource region, identifying pilot-free symbols free of the pilot signals in the plurality of symbols, arranging sacrifice carriers for a first region of a group of symbols in the pilot-free symbols at a first density for a first communication station, and arranging sacrifice carriers for a second region of the group of symbols in the pilot-free symbols at a second density for a second communication station, the first communication station mobile with respect to an access communication station at a first relative speed and the second communication station is mobile with respect to the access communication station at a second relative speed, and wherein the first density of sacrifice carriers is greater than the second density of sacrifice carriers if the first relative speed is greater than the second relative speed. | 08-28-2008 |
| 20100002786 | SIGNAL DETECTING METHOD AND RECEIVER USING THE SAME - A signal detecting method and a receiver using the same are provided. The method includes the following steps. A receiving signal vector y is received through a number of channels, wherein the receiving signal vector y corresponds to a transmitting signal vector x transmitted by at least one of the channels. A channel matrix H is determined, wherein the channel matrix H represents at least one of the channels. A factorization matrix D is chosen, wherein D is invertible to make the channel matrix H expressed as H={tilde over (H)}D, and {tilde over (H)} is a corresponding channel matrix. The factorization matrix D is determined to make an expected value of the signal estimate error become smaller. The receiving signal vector y is detected to estimate the transmitting signal vector x according to the corresponding channel matrix {tilde over (H)} and the factorization matrix D. | 01-07-2010 |
| 20100239032 | SYSTEM AND METHOD FOR PRECODING AND DATA EXCHANGE IN WIRELESS COMMUNICATION - A method for a first user terminal to receive data from a second user terminal, wherein the first and second user terminals communicate with a transmitting terminal. The method includes: transmitting a first message to the transmitting terminal; receiving a signal from the transmitting terminal, the received signal including information regarding the first message and a second message transmitted from the second user terminal to the transmitting terminal; and decoding, based on the first message, the received signal to receive the second message. | 09-23-2010 |

| 20090016371 | METHOD FOR CONSTRUCTING FRAME STRUCTURES - A method of constructing a frame structure for data transmission, the method comprising generating a first section comprising data configured in a first format compatible with a first communication system, generating a second section following the first section, the second section comprising data configured in a second format compatible with a second communication system, wherein the second format is different from the first format, generating at least one non-data section containing information describing an aspect of data in at least one of the first section and the second section, and combining the first section, the second section and the at least one non-data section to form the frame structure. | 01-15-2009 |
| 20090016464 | Method of and Generator for Generating Preamble Sequences in Communication Systems - A method forms a preamble sequence in a wireless communication system. The method comprises determining a value K related to a time-domain characteristic of the wireless communication system so that a time-domain preamble sequence includes a number of K waveforms similar in shape to one another having a linear phase shift, identifying a first preamble sequence for a first band, the first preamble sequence having a first length not dividable by K, identifying at least one second preamble sequence each for a second band, the at least one second preamble sequence having at least one second length, identifying the length of a third preamble sequence, the length of the third preamble sequence equal to a sum of the first length and the at least one second length, determining whether the time-domain characteristic is maintained when the one or more of the at least one second preamble sequence is concatenated with the first preamble sequence, modifying one or more of the at least one second preamble sequence if the time-domain characteristic is not maintained when concatenated, and forming the third preamble sequence by concatenating the first preamble sequence and the at least one second preamble sequence having one or more second preamble sequence modified. | 01-15-2009 |
| 20090067543 | Method and Apparatus for Multi-Rate Control in a Multi-Channel Communication System - An apparatus for data processing in a multi-channel communication system is provided. The apparatus includes an encoder configured to encode a number of bits for transmission via channels in the multi-channel communication system into coded bits and split the coded bits into a number of first sets of bits at a first ratio, a number of first rate units coupled to the encoder, each of the first rate units being configured to adjust one set of the first sets of bits in size at at least one rate, and a controller configured to assign the first ratio to the encoder and the at least one rate to each of the first rate units based on conditions of the channels. | 03-12-2009 |
