In this paper we present preamble design for millimeter-wave single carrier wireless personal area networks. Several factors are considered for a successful preamble design, such as sequence complexity, operation range, associated delay, robustness to frequency offset. Complementary Golay sequences are selected, which combine flexibility and performance. Simulation results indicate at optimum threshold...
In order to design a simple and highly accurate channel estimator for wireless personal area network systems, this paper proposes Golay sequence aided channel estimation. To evaluate the performance of proposed channel estimation, bit error rate performance of single-carrier transmission with frequency-domain equalization has been analyzed by computer simulation. When 8PSK modulation and Reed-Solomon...
The paper describes a low complexity tree-structure based user scheduling algorithm in a MLD-based multi-user multiple-input multiple-output (MIMO) wireless systems. An M-branch selection algorithm, which selects M most-possible best branches at each step, is proposed to maximize the whole system sum-rate capacity. To make this work more feasible, some implementation problems such as complexity reduction,...
The paper presents a feasible frequency domain pre-equalization (pre-FDE) proposal in order to reduce the number of frequency domain equalizer (FDE) in a piconet. The pre- equalization scheme based on the cross-layer design on both physical layer and MAC layer is proposed and investigated in millimeter-wave 60-GHz wireless personal area networks (WPANs). The physical structure is designed so that...
