This paper presents an efficient solution to recovering data pixels of images that have undergone optical and electrical channel impairments in holographic data storage systems. The channel impairments considered include interpixel interference, three types of misalignment, and noise. The proposed misalignment-compensation scheme, consisting of realignment(More)

Section V concludes posal [1], a MIMO-OFDM baseband receiver design for nextthis paper. generation WLAN is proposed. A MIMO-OFDM receiver with algorithms for timing and frequency synchronization and MIMO II. SYSTEM MODEL DESCRIPTION AND PACKET FORMAT detection is designed(More)
A dual mode 2×2 MIMO OFDM & OFDMA receiver is implemented with shared hardware resources. This dual mode receiver functions well in both static and mobile channels. It follows the specification requirement of EWC HT PHY V1.27 and IEEE 802.16e-2005, and proposes a PHY baseband simulation model to meet the specifications. Additionally,(More)
An iodine-modified Au(111) surface, (I/Au(111)), was used as a substrate to prepare a C 60 adlayer by self-organization in a benzene solution. A highly ordered C 60 adlayer was successfully prepared due to the moderate C 60-I/Au(111) interaction. Two lattice structures, (2 square root 3 x 2 square root 3) R30 degrees and p(2 x 2), were imaged for this C 60(More)
This paper presents hardware implementation of an efficient solution to recovering gray-scale data pixels of images that have undergone interpixel interference in holographic data storage systems. The adopted algorithm, called the turbo receiver using interference-aware dual-list (TRIDL) detection, enjoys benefits of low error rate performance and low(More)

This paper presents improved formula accuracy for quality factor Q of thin film bulk acoustic resonators (FBARs) with close series and parallel resonance frequencies. Traditionally, the series and parallel resonance behaviors are treated independently. The FBAR piezoelectric coupling coefficient is only a few percentages with the series and parallel(More)
