Abstract: In 60 GHz WiGig/IEEE 802.11ad, Orthogonal Frequency Division Multiplexing (OFDM) is used to achieve higher throughput. However, OFDM has one problem of high Peak-to-Average Power Ratio (PAPR) caused by the summing up of the large number of subcarriers. A high PAPR signal degrades the efficiency of power amplifier (PA) and may cause spurious emissions because of the PA non linearity. In order to reduce PAPR, Generalized Frequency Division Multiplexing (GFDM) which has the characteristics of both single carrier and multi carrier transmission has been studied. By introducing GFDM, the number of subcarriers can be decreased while still maintaining a high throughput.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of beamforming training. For example, an apparatus may include a transmitter, a receiver, and a controller to repeat a beamforming training sequence including a transmit (Tx) mode and a receive (Rx) mode, at the Tx mode the transmitter is to transmit a directional Tx training signal to a wireless communication device, and at the Rx mode the receiver is to be at an omnidirectional Rx state, wherein subsequent to successful receipt of a directional Rx training signal from the wireless communication device at the receiver, the transmitter is to transmit the directional Tx training signal including an Rx beam indication to indicate a beam direction of the Rx training signal.
