The method includes: dividing m transmitting antennas into one or more groups to form u transmitting ports, wherein transmitting antennas in different groups are uncorrelated, and m is greater than or equal to u; forming p data flows using a multiple-input multiple-output (mimo) mode, wherein p=u/2, and p is less than or equal to a number of receiving ports; and mapping a group of 2p modulation symbols, including two modulation symbols of each data flow, to a resource element pair to form space frequency block code (sfbc) coding relationships with each other, and transmitting the group of 2p modulation symbols on the u transmitting ports.

Signal processing

A method of processing an amplitude-modulated analogue signal at a carrier frequency fc comprises: digitising the analogue signal to produce an input bit stream that represents the amplitude of the analogue signal; generating an in-phase reference bit stream that is synchronous to the carrier frequency fc and represents an in-phase digital reference signal substantially in the form of a sine and/or cosine wave; and multiplying the input bit stream with the in-phase reference bit stream to produce an output bit stream representing the amplitude modulation of the analogue signal.. .
