ABSTRACT

The spectacular development of information technologies over the last two decades has ushered in a new era that increasingly relies on ubiquitous wireless connectivity enabled by advances in wireless communications. Despite numerous progresses in recent years, challenges to high-speed wireless communications remain. Unlike wireline communication systems, wireless channels are prone to physical impairments such as interferences, path loss, channel fading, shadowing, and multipath distortions. These obstacles can severely limit the future enhancement of wireless system capacity for communications and often hamper the practical dependability of wireless links.
