Single-stream Communication Using Orthogonal Signal Division Multiplexing with Multiple Antennas
Orthogonal signal division multiplexing(OSDM)is a new information transmission method using the Kronecker product between the rows of an IDFT matrix and the data sequences.This technique is designed to keep orthogonality among the data sequences over the frequency-selective fading channel.By sharing one data sequence as a pilot between the transmitter and the receiver,the receiver can obtain the channel matrix from the pilot and obtain the message by solving simultaneous equations.This technique has been extended to multistream communication with multiple antennas by the author.However,it was found that the simultaneous equation sometimes become ill-conditioned,which results in a loss of performance.This problem could be avoided with an increase in the number of antennas in the receiver.However,the increase in complexity remains an issue.In this paper,single-stream communication using OSDM with multiple antennas is proposed.By designing the data sequences in the transmitter,the ill-condition problem can be avoided with less complexity.The simulation results suggest that single-stream communication with multiple antennas can achieve better bit-error rate performance compared to the multistream case,with less complexity in exchange for an efficient data rate.
