Description

The purpose of this research project is to assess characteristics of communication systems hardware at speeds that are currently viable in research settings. The specific characteristic that is studied is the error or miss-assessment of a unit of data. Two kinds of errors are considered: errors at the sending end of the system and errors at the receiving end of the system. This is consideration is based on current hardware limitations of the communication systems. The above mentioned errors are considered in two different communication systems Quadrature Phase Shift-Keying (QPSK) and Quadrature Amplitude Modulation 16-bit (QAM-16). QPSK is the current method of transmitting high speed data such as the home internet service provider. QAM-16 is not yet being used in the market but it is under intensive industry research. The scope of this project is to analyze the currently available theoretical data on the subject and create software simulations to assess the levels of the errors. The data is then compared against the error correction abilities currently available (Forward Error Correction FEC). Another comparison is to the acceptable level of noise also called interference, which is always present in any communication system. The comparisons determine the quality of the communication system while the simulations attempt to present a clear picture of the physical variables in a communication system.
