This paper proposes a framework for combined source-channel coding for a power and bandwidth constrained noisy channel. The framework is applied to progressive image transmission using constant envelope M-ary phase shift key (M-PSK) signaling over an additive white Gaussian noise channel. First, the framework is developed for uncoded M-PSK signaling (with M = 2k). Then, it is extended to includ...

Recently, sphere detection has emerged as a powerful means of finding the maximum likelihood solution to the detection problem for multiple-antenna (MIMO) systems. In this paper, we analyze the performance and computational complexity of different sphere detectors and compare it with that of already known MIMO receiver techniques, in uncoded as well as coded transmission1. We propose a number o...

Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it more immune to channel impairments. In addition to coding, the best modulation techniques available today are MSK (Minimum Shift Keying) and G...

High-rate optimized linear dispersion (LD) codes have been investigated extensively in theory and by simulation throughout the last years. Regardless of the findings of the research so far, little work has been performed to investigate the performance of such codes in a realistic transmission system. We implemented an optimized full-rate full-diversity space-time block code, derived by Damen, o...

Transposition errors fundamentally undermine reliability and capacity in molecular communication, when individual particles are used for information encoding. Recently, several channel coding techniques have been proposed for mitigating the transposition effect. The presented techniques show promising results for diffusion-based channels with drift. However, so far no performance evaluation has...

It is a common belief that multiple transmit antennas have to be placed far apart in order to avoid undesired effects such as mutual coupling, changing beampatterns, antenna mismatching losses, and correlation. The following radio communication setup is considered: two l=4monopole ground-plane transmit antennas, a single receive antenna, 4QAM modulation, Alamouti space-time coding, uncoded sing...

Batch codes are a family of codes that represent a distributed storage system (DSS) of n nodes so that any batch of t data symbols can be retrieved by reading at most one symbol from each node. Fractional repetition codes are a family of codes for DSS that enable efficient uncoded repairs of failed nodes. In this work these two families of codes are combined to obtain fractional repetition batc...

A technique for tracking the orientation and position of a nearplanar surface in real-time is presented. It uses the principle of structured light to determine 3D surface shape, by the projection of a dense pattern of uniform (uncoded) stripes. In order to estimate pose a weighted least-squares plane is fitted to the 3D data. As an example the technique is applied in a gaming environment where ...

The radio over the free space optical (RoFSO) communication system has become a popular research topic in 5G recent years. Atmospheric turbulence typically degrades performance of RoFSO system. Multiple input multiple output, aperture averaging, error-correcting codes, and robust modulation are standard mitigation techniques used to reduce effects atmospheric turbulence. In this paper, Reed Sol...
