Signal sequence estimation

摘要

In a spatial modulation multiple-input-multiple-output (SM-MIMO) wireless communication system, multiple transmitting antennae and multiple receiving antennae may be utilized to respectively transmit and receive wireless signals for the communication. A selection of a combination of the multiple transmitting antennae may be configured to represent one or more binary digits in a signal sequence. The signal sequence may be produced at the receiving end without the knowledge of the selection of the combination of the multiple transmitting antennae.

主权项

1. A method to estimate one or more signal sequences, comprising:
identifying multiple combinations of one or more transmitting antennae; receiving one or more wireless signals transmitted by one of the identified combinations of the one or more transmitting antennae; generating multiple groups of symbols that respectively correspond to one of the identified combinations of the one or more transmitting antennae; calculating a value for each of the multiple groups of symbols; selecting, from the multiple groups of symbols, the group of symbols having the lowest calculated value; and producing the one or more signal sequences based on the selected group of symbols in accordance with a predetermined mapping table.
