Abstract:
The present invention provides an FBMC transmit diversity transmission method, a transmit end apparatus, and a receive end apparatus. The method includes: obtaining a to-be-transmitted data sequence, where the to-be-transmitted data sequence includes 2*M*N pieces of data; performing transmit diversity processing on the to-be-transmitted data sequence to obtain FBMC signals of a first antenna and a second antenna, where a precoding matrix is (I) or (II), a matrix that includes the FBMC signals of the first antenna and the second antenna is (III), a matrix that includes the to-be-transmitted data sequence is (IV), 0‰¤ i‰¤ M-1, 0‰¤ j ‰¤N-1, Y=WX, the 2*M*N pieces of data of the to-be-transmitted data sequence are denoted by x (0) ( k,l ) and x (1) ( k,l ), 0‰¤ k‰¤ M-1, 0‰¤ l ‰¤N-1, FBMC signals of the first antenna and the second antenna on an r th subcarrier and an s th symbol are denoted by y (0) ( r , s ) and y (1) ( r , s ), 0‰¤ r ‰¤2M-1, and 0‰¤ s ‰¤N-1; and transmitting the FBMC signals of the first antenna and the second antenna.
Abstract:
An FBMC signal transmitting method and receiving method, a transmitter, and a receiver are provided. The transmitting method includes: generating offset quadrature amplitude modulation OQAM symbols included on at least two subbands; mapping an OQAM symbol on each subband onto a respective subcarrier to obtain a frequency-domain signal, where a first frequency interval exists between adjacent subcarriers in a same subband, a second frequency interval exists between adjacent subcarriers that belong to two adjacent subbands, the second frequency interval is a sum of the first frequency interval and a guard band interval, and the guard band interval is a fractional multiple of the first frequency interval; generating an FBMC signal out of the frequency-domain signal; and transmitting the FBMC signal to a receiver.
