Using sequences for symbol timing synchronization in single-carrier modulation MIMO communication systems

摘要

A method for symbol timing synchronization in multiple-input multiple-output (MIMO) communication, the method including transmitting a first symbol sequence including a preamble symbol sequence S1 from a first transmitting location, transmitting a second symbol sequence from a second transmitting location, the first and second symbol sequences being modulated onto a same carrier frequency, receiving a first mixture of the first and the second symbol sequences at a first receiving location, cross correlating the first mixture with a symbol sequence P1 thereby producing a first correlation output, and determining a first timing offset for receiving the first symbol sequence based, at least in part, on the first correlation output. Related apparatus and methods are also described.

1. A method for symbol timing synchronization in multiple-input multiple-output (MIMO) communication, the method comprising:
transmitting a first symbol sequence comprising a preamble symbol sequence S1 from a first transmitting location; transmitting a second symbol sequence from a second transmitting location; the first and second symbol sequences being modulated onto a same carrier frequency; receiving a first mixture of the first and the second symbol sequences at a first receiving location; cross correlating the first mixture with a symbol sequence P1 thereby producing a first correlation output; and determining a first timing offset for receiving the first symbol sequence based, at least in part, on the first correlation output, and on a measure of symmetry of values of the first correlation output about a high value of the correlation output.
