Abstract
Many applications nowadays require high data rates, while the contemporary technology cannot support such high rate demand, especially for indoor wireless communications. To achieve a high data rate for indoor channels, 60 GHz technology has emerged as one of the most promising candidates. There are many advantages in 60 GHz technology, such as very high achievable data rates, huge unlicensed bandwidth available worldwide, and little intersystem interference. In addition, systems such as orthogonal frequency division multiplexing (OFDM) systems have been proposed for the 60 GHz indoor channels due to the remarkable properties, such as simpler channel equalization and high spectral efficiency. Yet practical analysis for OFDM systems over 60 GHz indoor channels is still rare in the literature. In this thesis, by the aid of the extended density function, the average effect of the random arrivals is derived and a special spatial domain randomness existing in the 60 GHz indoor channels is also included. An exact signal-to-interference-plus-noise ratio (SINR) analysis of OFDM systems over 60 GHz indoor channels is then provided. Finally, some discussions, mainly focused on the spatial domain, based on the SINR analysis are given.
