In 2001, the Federal Communications Commission (FCC) allocated an unlicensed 7-GHz wide band in the radio-frequency (RF) spectrum from 57 to 64 GHz for wireless communications (FCC, 2001). This is the widest portion of radio-frequency spectrum ever allocated in an exclusive way for wireless unlicensed applications, allowing multi-gigabit-per-second wireless communications. Other countries worldwide have allocated the 60-GHz band for unlicensed wireless communications (Japan (Ministry of Internal Affairs and Communications [MIC]), 2008), Australia (Australian Communications and Media Authority [ACMA], 2005), Korea (Ministry of Information Communication of Korea, 2006), Europe (ETSI, 2006)), allowing in principle a universal compatibility for the systems operating in that band. Fig. 1 shows the 60GHz frequency band allocations in USA, Canada, Japan, Australia, Korea and Europe. Another reason that makes the 60-GHz band very attractive is the coverage range, which is limited to about 10m caused by the dramatic attenuation in the signal propagation. This is due primarily to the high path loss at 60GHz, and moreover the peak of resonance of the oxygen molecule, allowing several Wireless Personal Area Networks (WPANs) to operate closely without interfering. Moreover, at the millimetre-waves (mm-waves) it is easier to implement very directional antennas, thus allowing the implementations of highly directional communication links. Line-Of-Sight (LOS) communication may help in alleviating the design challenges of the wireless transceiver. One of the most promising applications that will benefit of the huge amount of bandwidth available in the 60-GHz range is the uncompressed High-Definition (HD) video communication (Singh, et al., 2008). The reasons that make attractive the uncompressed video streaming are that compression and decompression (codec) in transmitter and receiver, respectively, exhibit some drawbacks such as latency which can not be tolerated in real time applications (e.g. videogames), degradation in the video quality, and compatibility issues between devices that use different codec techniques. The HD video signal has a resolution of
