1. the pilot signal transmission method of the multi-transmitting antenna system of an enhancing, the quantity of described multiple transmit antennas is N, each transmitting antenna is according to a kind of known pilot frequency design pilot signal transmitted, every kind of corresponding a kind of expense of pilot frequency design, the expense of total M kind pilot frequency design is different, and described method comprises the steps:

  • According to the expense of pilot frequency design, N pilot frequency design is divided into M pilot frequency design group, each pilot frequency design group comprises the identical N/M of an expense pilot frequency design;

    Accordingly, N transmitting antenna is divided into the M group, every group comprises N/M transmitting antenna;

    At initial time, transmitter is that every group of transmitting antenna distributes a pilot frequency design group, and each transmitting antenna in each antenna sets is selected a pilot frequency design pilot signal transmitted in this pilot frequency design group that is assigned with for use;

    Every time T, transmitter is each transmitting antenna set of dispense pilot frequency design group again, and each transmitting antenna in each antenna sets is selected a pilot frequency design pilot signal transmitted in this pilot frequency design group that is assigned with for use.
