In this paper, a precoded and iteratively detected downlink multiuser system is proposed, which is capable of operating in rankdeficient scenarios, when the number of transmitters exceeds the number of receivers. The literature of uplink space division multiple access (SDMA) systems is rich, but at the time of writing there is a paucity of information on(More)
We analyze a precoded and iteratively detected downhink multiuser system employing imperfect Spatio-Temporal Channel Impulse Response at the Transmitters (ST-GIRT) with the aid of Extrinsic Information Transfer (EXIT) charts. A Precoded Iterative DownLink Space Division Multiple Access (PI-DL-SDMA) system proposed in our previous research is further(More)
The literature of up-link SDMA systems is rich, but at the time of writing there is a paucity of information on the employment of SDMA techniques in the down-link. Hence, in this paper a Space Division Multiple Access (SDMA) down-link (DL) multi-user communication system invoking a novel low-complexity Maximum Likelihood (ML) space-time detection technique(More)
In this treatise, a jointly optimized Bit Interleaved Coded Modulation using Iterative Decoding (BICM-ID) and Luby Transform (LT) coding scheme was proposed for the sake of attaining the best possible performance, when communicating over the wireless Internet. This scheme is particularly attractive when handling packetized wireless Internet data traffic(More)
OBJECTIVE To investigate the therapeutic effects and safety of photodynamic therapy on choroidal neovascularization (CNV) of pathologic myopia. METHODS Retrospective noncomparative clinical data of 27 cases with CNV complicated from pathologic myopia (32 eyes) and treated with PDT, the parameters including the study were fundus characteristics,(More)
An adaptive detection scheme is proposed on the very fast detection algorithm for Space-time block code in IEEE 802.11ac. At first, QR decomposition is applied to the channel matrix for getting an upper triangular matrix and has been achieved the required number of candidate constellation points around the maximum likelihood (ML) points without considering(More)
In this paper, we revisit the received signal strength (RSS)-based target localization technique presented in Vempaty <italic>et al.</italic>, where a simple threshold quantizer was employed to quantize the RSS values prior to sending them to the fusion center. It was shown that the probability of misclassification of the distributed classification fusion(More)
