The objective of this research is to investigate efficient signal processing algorithms for high data rate wireless communications with advanced wireless devices. Portable wireless devices need to support applications such as real-time high resolution video and mobile gaming with high data rate and computational requirements. Mobile computing devices now use multiple computing cores. These processors perform the same amount of computation per unit time as single core processors while requiring much less power. Making effective use of this new class of processors requires careful management of the information exchanged between the cores. Current wireless devices' signal processing algorithms consist of sequential calculations which do not map efficiently onto multiple cores. We will develop new signal processing algorithms with parallel calculations which execute efficiently on multiple cores. Trade-offs between calculation duration, parallelization, and final error performance will be investigated. The receiver trade-offs in terms of parallelization are not well explored in the current literature. The new signal processing algorithms will enable small low power advanced wireless devices to support highly reliable, high data rate communications applications.
