This paper considers the performance of single parity check (SPC) multidimensional product codes in an Additive White Gaussian Noise channel. Asymptotic performance bounds are derived and compared to simulation results. A new code structure based on SPC product codes is introduced. This structure involves interleaving between the encoding of each dimension.… (More)
We propose a simple class of encoding/decoding techniques that can be used to improve the information outage rate of certain multiple-input-multiple-output (MIMO) systems. Gains in outage rate can be achieved at low to moderate signal-to-noise ratios in MIMO systems that have fewer receive antennas than transmit antennas. This performance improvement is due… (More)
This paper investigates the performance and analysis of both parallel and serial con-catenation of single parity check (SPC) product codes in an Additive White Gaussian Noise (AWGN) channel. Asymptotic performance bounds are derived and compared to simulation results.
The parallel and serial concatenation of codes is well established as a practical means of achieving excellent performance. In this paper, we introduce the parallel and serial concatenation of single parity check (SPC) product codes. The weight distribution of these codes is analyzed and the performance is bounded. Simulation results confirm these bounds at… (More)
— To date there has been little work done on multilevel codes for the space-time environment. In this paper we develop multi-dimensional space-time multilevel codes (ST-MLCs), which partition the 2Nt-dimensional signalling space that spans all Nt transmit antennas. The partitioning is designed to reduce the complexity of detection/ decoding. We also develop… (More)
1 In the current Canadian regulatory environment, a mutual fund company is able to delete the history of an underperforming fund from public record by merging it with another fund. This paper addresses the effects of this rule on the super-concentrated group of Canadian mutual fund mergers that involved eCommerce portfolios between 2001 and 2004.
A process of data acquisition and analysis of text files for the purpose of following the insurgence and growth of words in the English language is reported. Pitfalls that were encountered and the solutions that were found to these problems are also discussed. The question of whether the Zipf-Mandelbrot law applies to the distribution of words in a language… (More)
