SPATIAL MODULATION MULTIPLE-INPUT-MULTIPLE-OUTPUT (SM-MIMO) SYSTEM

摘要

In an SM-MIMO wireless communication system, multiple transmitting antennae may be utilized to transmit wireless signals that carry signal sequences. A selection of the multiple transmitting antennae may be configured to represent a portion of the signal sequences so that channel state information (CSI) is not required at the receiving end of the SM-MIMO system.

1. A method for modulating sequences in a wireless communication system, comprising:
receiving multiple sections of a divided signal sequence, each of which includes multiple binary digits; for each of the multiple sections, selecting a first one of multiple transmitting antennae during a time interval in accordance with at least a portion of the multiple binary digits; for each of the multiple sections, generating multiple modulation symbols to be transmitted by the selected first one of the multiple transmitting antennae during the time interval in accordance with other portions of the multiple binary digits; generating a matrix symbol by combining the generated multiple modulation symbols of consecutive ones of the multiple sections; and switching, from the first one of the multiple transmitting antennae, to a second one of the multiple transmitting antennae if the selected first one of the multiple transmitting antennae was selected in a preceding time interval for the matrix symbol.
