Abstract

This disclosure describes methods, apparatus, and systems to increase the transmission data rate in wireless networks, for example, by using one or more Multiple Input Multiple Output (MIMO) and/or channel bonding techniques. In one embodiment, the disclosure describes the use of Golay Sequence Sets (GSS) to define guard intervals (GIs) for single carrier (SC) single channel bonding and multiple input multiple output (MIMO) transmission. In various embodiments, the disclosure describes the design of guard interval sequence for 3 types of guard intervals having lengths that can be classified as short, medium, and long. In another embodiment, the disclosure defines the guard interval for single channel transmission channel bonding and for MIMO transmission.
