Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

At Skyworks Solutions throughput of the back side through-wafer via etch process was low because of a high rework rate. The high rework rate was due to an organic residue blocking the etch. A process was first developed to remove the residue and then integrated into the via etch process. The optimized via etch process resulted in a reduction in reworks and a significant increase in process thro...

A general expression for the channel throughput of slotted ALOHA under Nakagami fading is obtained assuming different fading statistics and unequal average power levels for the desired and the interfering packets. The expression provides a better alternative to the previously reported expressions derived under similar conditions. With this general expression the effect of the use of modulation ...

This paper proposes a hardware architecture of Kbest-based 4× 4 MIMO decoder that supports up to 256-QAM. The novelties such as Direct Expansion, and 2D Sorter play important roles on reducing the complexity of the decoder. In addition, the most complex operators such as divider and multiplier are eliminated in this design. As compared to the previous works, the proposed decoder achieves the hi...

This work presents the experimental results related to performance measurements in GSM and GPRS cellular data networks. Two Mobile Terminals were used, in order to take place the scenario. Power Level, Power vs Time, Modulation Analysis, Modulation Spectrum, (BER) Bit Error Rate and Throughput were considered in this analysis.

In this paper, an integer programming approach is introduced to construct Unequal Error Protection (UEP) codes for multiuser broadcast channels. We show that the optimal codes can be constructed that satisfy the integer programming bound. Based on the bound, we compute asymptotic code rate and perform throughput analysis for the degraded broadcast channel.

In this paper we suggest a novel idea to improve the Throughput of a rapidly changing WiFi channel by exploiting the standard aggregation schemes in IEEE 802.11ac networks, and by transmitting several copies of the same MPDU(s) in a single transmission attempt. We test this idea in scenarios where Link Adaptation is not used and show a significant improvement, in the order of tens of percents, ...

The influence of code synchronization errors on the performance of direct-sequence spread-spectrum (DS/SS) communication systems is investigated. Insight is gained in the degradation of some basic performance parameters due to the tracking bias of a noncoherent delay lock loop (DLL). The performance parameters investigated are the bit-error probability, throughput and delay. Numerical results s...

In wireless networks, interference from adjacent nodes that are concurrently transmitting can cause packet reception failures and thus a significant throughput degradation. The interference can be simply avoided by assigning different orthogonal channels to each interfering node. However, if the number of orthogonal channels is smaller than that of interfering nodes, some adjacent nodes have to...
