“…HSDPA (Benkeser et al, 2009) WCDMA (Frigon et al, 2007) The throughput of the turbo decoder is estimated as 21.37 Mb/s which is 5.7% higher than reference. On the other hand, throughput of the overall system (MIMO HSDPA) also finds a remarkable improvement i.e., 13.5 Mb/s; whereas (Benkeser et al, 2009) achieves 10.8 Mb/s ( Table 3).…”

A novel channel based rescheduling scheme for modern turbo convolution code is proposed by the inclusion of suboptimal and low-complex max-log-MAP algorithm. Demands for dedicated custom solutions in mobile communications and its related applications leads to a reconfigurable architecture for Turbo convolution code. This study comprises the design and performance evolution of the proposed reconfigurable architecture for channel coding scheme in MIMO-High Speed Downlink Packet Access (MIMO-HSDPA). To attain effective performance close to shannon limit in a multi channel system, flexible reconfigurable architecture is realized with 28 nm cyclone V GX 5CGXFC5C6 FPGA. We achieved throughput of 13.5 Mbps compared with the conventional HSDPA standards while consuming 53 mW.

Abstract-In this paper, we develop a combinatorial method for the evaluation of the functional yield of defect-tolerant systems-onchip (SoC). The method assumes that random manufacturing defects are produced according to a model in which defects cause the failure of given components of the system following a distribution common to all defects. The distribution of the number of defects is arbitrary. The yield is obtained by conditioning on the number of defects that result in the failure of some component and performing recursive computations over a reduced ordered binary decision diagram (ROBDD) representation of the fault-tree function of the system. The method has excellent error control. Numerical experiments seem to indicate that the method is efficient and, with some exceptions, allows the analysis with affordable computational resources of systems with very large numbers of components.Index Terms-Combinatorial method, defect-tolerant systems-on-chip (SoC), manufacturing defects, reduced ordered binary decision diagram (ROBDD), yield.

“…Besides the traditional method of data detecting, there is another method for signal reception by use of two antennas, named diversity reception [9]. In most cases, diversity reception is implemented by use of two antennas [10][11] and this method is mostly realized for base stations in cellular networks. The distance between antennas is about 10 wavelengths.…”

This work shows prospects of application of transceiving stations with two antennas to provide an optimal routing in peer-to-peer mobile wireless networks. Route discovery for data transmission from source to destination is implemented by use of two antennas for signal reception at each station in the network. An optimal route discovery becomes possible due to detection of angular position of neighbors situated in a radio access area. Detection of angular position allows delegating functions of a router to optimally situated neighbors (three and less) and, in consequence, the overall quantity of intermediate stations that perform functions of a router decreases by several times (for example by 18 times in comparison with neural method).
