Abstract:
1. A method for implementing transmitting diversity, the method comprising: receiving a symbol from a destination mobile terminal, by a mobile terminal which is in a same mobile terminal group with the destination mobile terminal, wherein the symbol is also sent from the destination mobile terminal to a base station; and processing, by the mobile terminal, the symbol and transmitting the symbol processed to the base station; wherein processing the symbol and transmitting the symbol processed to the base station comprises: processing, by the mobile terminal, the symbol according to space-time coding rules, and transmitting the symbol processed to the base station via time division; wherein transmitting the symbol processed to the base station via time division comprises: transmitting, if the symbol is a complex number signal and the number of mobile terminals in the mobile terminal group is N, the symbol, a reciprocal value of the symbol, a conjugation of the symbol or a negative conjugation of the symbol to the base station at 2N consecutive symbol periods by the N mobile terminals; and wherein 2N*N transmitted signals are determined by a 2N*N quasi-orthogonal matrix, N*N elements in the first N rows of the 2N*N quasi-orthogonal matrix constitute an N-order orthogonal matrix and N*N elements in the last N rows are a negative conjugation of the N*N elements in the first N rows, wherein the N is not equal to 2.
