DESIGN OF A CONVERGENCE-AWARE BASED EXPECTATION PROPAGATION ALGORITHM FOR UPLINK MIMO SCMA SYSTEMS


Sparse code multiple access (SCMA) uses multi-dimensional sparse codewords to transmit user data. The expectation propagation algorithm (EPA) exploiting the sparse property shows linear complexity growth and thus is preferred for multi-user detection. To further reduce the complexity, a convergence-aware based EPA for uplink MIMO SCMA systems is proposed. Techniques including user termination, antenna termination, and codebook reduction are adopted. The user termination must be combined with the iteration constraint to avoid misjudgement.

DECODING HIGH-THROUGHPUT JPEG2000 (HTJ2K) ON A GPU


High-throughput JPEG2000 (HTJ2K), also known as JPEG 2000 Part 15, is the most recent addition to the JPEG2000 suite of coding tools. The file extension JPH has been designated for compressed images employing this new part of the standard. This new part describes a “fast” block coder for the JPEG 2000 format, while retaining most other JPEG2000 features and capabilities intact.

ACCURACY EVALUATION BASED ON SIMULATION FOR FINITE PRECISION SYSTEMS USING INFERENTIAL STATISTICS


The conversion of an algorithm to fixed-point arithmetic is commonly achieved with a large and fixed-number of simulations. Nevertheless, when simulating a fixed and ar- bitrary large number of samples, no confidence information is given on the characterization, and this method is often time-inefficient. To overcome this limitation, we propose a new method for noise evaluation. The error induced by fixed-point coding is statistically characterized to compute the noise power with an adaptive and reduced number of simulations.

The Direction Cosine Matrix Algorithm in Fixed-Point: Implementation and Analysis


Inertial navigation allows tracking and updating the position and orientation of a moving object based on accelerometer and gyroscope data without external positioning aid, such as GPS. Therefore, inertial navigation is an essential technique for, e.g., indoor positioning. As inertial navigation is based on integration of acceleration vector components, computation errors accumulate and make the position and orientation estimate drift.

PARAMETRIC HEAR THROUGH EQUALIZATION FOR AUGMENTED REALITY AUDIO


Augmented Reality (AR) audio applications require headphones to be acoustically transparent so that real sounds can pass through unaltered for natural fusion with virtual sounds. In this paper, we consider a multiple source scenario for hear through (HT) equalization (EQ) using closed-back circumaural headsets. AR headset prototype (described in our previous study) is used to capture real sounds from external microphones and compute the directional HT filters using adaptive filtering.
