Parity check matrix storing method, block ldpc coding method, and apparatus using parity check matrix storing method
TL;DR: In this article, a low density parity check (LDPC) encoding method was proposed and an apparatus thereof was presented. And the present invention relates to the LDPC encoding method and the apparatus thereof.
Patent
Encoder using low density parity check codes and encoding method thereof
TL;DR: An encoder using LDPC (low density parity check) codes, and an encoding method is presented in this article. But the encoder does not have the ability to generate parity check matrices.
Journal ArticleDOI
QR-LRL Signal Detection for Spatially Multiplexed MIMO Systems
TL;DR: It is shown that the selection of the first layer impacts the error performance significantly, and based on the observation, a novel signal detection method QR-LRL is proposed, which is shown to be the best choice in terms of noise enhancement in detecting the other layers.
Patent
Method and apparatus for uplink timing synchronization with ranging signal in mobile communication system
TL;DR: In this paper, an initial ranging request signal from a subscriber station to a base station is received and the base station generates initial ranging information including delay time information to the subscriber station, and receives uplink data delayed and transmitted using a delay time from the user.
Patent
Subcarrier allocation apparatus and method, subcarrier de-allocation apparatus and method in ofdm system
TL;DR: In this article, a logical index generator (142) and an intermediate index converter (144) were used to allocate a data subcarrier to a physical index, the logical index being included with only data sub-carriers and the physical index indicating a location of substantial subcarriers within a symbol.
