653 [9] D. Chen and T. Saito, " A new method to reduce the complexity of joint detection algorithm, " in Proc. Abstract—In this paper, a precoded and iteratively detected downlink multiuser system is proposed, which is capable of operating in rank-deficient scenarios, when the number of transmitters exceeds the number of receivers. The literature of uplink(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) multiuser communication system invoking a novel low-complexity Maximum Likelihood (ML) space-time detection technique(More)
We analyze a precoded and iteratively detected downlink multiuser system employing imperfect Spatio-Temporal Channel Impulse Response at the Transmitters (ST-CIRT) 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)
— When an iterative-decoding aided system is configured to operate at a near-capacity performance, an excessive complexity may be imposed by the iterative process. In this paper, we propose the novel framework of generic detection, which invokes appropriately amalgamated multiple detectors. Hence the proposed Irregular Generic Detection (IrGD) algorithm may(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 pack-etized wireless Internet data traffic(More)
