摘要: In an OFDM system, multiple (M) interlaces are defined for M non-overlapping sets of frequency subbands, and slots with fixed indices also defined. Data streams pilot mapped to slots, which in turn based on a slot-to-interlace mapping scheme that can achieve diversity good performance all slots. At transmitter, converter maps the interlaces. The includes multiplexers control unit. map scheme. unit generates at least one signal multiplexers. may be arranged controlled various manners depending receiver, complementary interlace-to-slot
