Abstract: Embodiments of the present invention provide a data transmission method and apparatus, and the method includes: modulating to-be-sent information bits according to a lower order constellation diagram, and generating 4m lower order modulation symbols; multiplying a precoding matrix Q by a column vector including every four lower order modulation symbols in the 4m lower order modulation symbols, to obtain 4m to-be-sent higher order modulation symbols corresponding to a higher order constellation diagram; and respectively and correspondingly sending the 4m to-be-sent higher order modulation symbols on different carriers of two antennas. The to-be-sent higher order modulation symbols include some or all to-be-sent information bits. Therefore, the same signal can be simultaneously sent on different carriers of multiple antennas, and frequency diversity and space diversity are implemented, so that transceiving performance of data transmission is improved.

Abstract: An electronically steerable antenna with dual polarization is provided, as well as a method for steering such an antenna. An example antenna may include a driven patch element having dual polarity for radiating or receiving a first beam with a first polarization and radiating or receiving a second beam with a second polarization. The antenna includes a parasitic patch element separated from the driven patch element and in a parasitic coupling arrangement to the driven patch element, as well as first and second tuning elements linked to the parasitic patch element to control first and second terminating impedances of the parasitic patch element, respectively. The first terminating impedance at least partly determines a direction of the first beam, and the second terminating impedance at least partly determines a direction of the second beam.

Abstract: It is possible to reduce the PAPR of an amplified signal communicated over bonded channels by applying different phase shifts to control fields communicated over the bonded channels. The phase shifts reduce the amount of constructive interaction between the control fields by shifting the peaks of the respective signals in the time domain. The control fields may include short training fields (STFs), channel estimation (CE) fields, or header fields communicated over bonded channels.
