This paper presents a novel low-complexity, hard output multiple-input, multiple-output (MIMO) detection algorithm and architecture for LTE and WiFi applications. Our method provides a well-defined tradeoff between computational complexity and performance. The proposed algorithm does not require QR decomposition as a preprocessing step, as is commonly needed in sphere detection (SD). Simulation results...
In this paper we propose a high performance bidirectional path preserving trellis search (PPTS) detector for multiple-input-multiple-output (MIMO) systems. The error analysis between single direction and bidirectional PPTS detector is given. We prove that the bidirectional PPTS detector can minimize the detection error effectively. Moreover, the proposed detector saves 10% hardware cost with a 0.1dB...
This paper presents a novel detection algorithm for soft-output, multiple-input multiple-output (MIMO) systems. The algorithm obtains a list of candidates used to calculate likelihood information in parallel and it includes two stages for tree searching, where each stage corresponds to one direction of the path selection process. The simulation results indicate that the algorithm achieves better performance...
Memory integrity verification has been widely used to protect off-chip memory from the tamper attacks. In this paper, we propose a new hash mechanism, multi-grained hash tree (MGT), to optimize the run-time performance of memory integrity verification. This new scheme adopts variable granularities to hash the nodes on different levels, and caches these nodes in a split hash cache. The experimental...
Spectrum sensing is a key technology of cognitive radio. The goal of spectrum sensing in this context is to achieve a high detection probability in order to avoid causing interference to the primary licensed users. Among the methods available for spectrum sensing, energy detection has been widely applied in hardware implementations. However, since previous work has been based on the traditional FFT,...
As the networking technology greatly advanced in past decades, wireless sensor networks (WSN) have been widely deployed and utilized in various areas. Security issues on WSN devices thus draw much attention. In order to ensure the security of IEEE802.15.4 WSN and to fulfill the strict limitations of area and energy, we propose an efficient scheme for AES-CCM architecture. We implement AES-CCM by taking...
