Higher timing detection probability

In this paper, we propose a fine time synchronization for a Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system. The proposed algorithm uses one more IFFT to find the timing offset, then correct it. The simulations show that comparing to the conventional algorithm using cross-correlation method, the proposed algorithm has a higher timing detection probability.

In this paper, we present a synchronization algorithm for Multi-Carrier CDMA (MC-CDMA) systems using a time-multiplexed synchronization channel. The simulations results show that a system using proposed algorithm has much higher timing detection probability than using other algorithms, especially in exponential decay multipath fading.

The problem of hardware Trojans is becoming more serious especially with the widespread of fabless design houses and design reuse. Hardware Trojans can be embedded on chip during manufacturing or in third party intellectual property cores (IPs) during the design process. Recent research is performed to detect Trojans embedded at manufacturing time by comparing the suspected chip with a golden chip that is fully trusted. However, Trojan detection in third party IP cores is more challenging than other logic modules especially that there is no golden chip.
