Signal transmitting method and apparatus using location division multiple access

A reference signal receiving apparatus, comprising:

• a first delay unit which is configured to delay a received reference signal for a first delay time;
• a second delay unit which is configured to delay the reference signal output from the first delay unit for a second delay time;
• and
• a first multiplexer which is configured to multiplex the reference signals output from the first and second delay units according to a control signal.

A data transmitting method comprising:

• delaying data to be transmitted by at least two delay times, wherein each of the at least two delay times occurs sequentially;
• multiplexing the data, which has been delayed, according to a control signal;
• and
• transmitting the data and a reference signal which corresponds to the data at an interval of delay time.

A data receiving method comprising:

• delaying reference signals by at least two delay times, wherein each of the at least two delay times occurs sequentially;
• multiplexing the reference signals, which have been delayed, according to a control signal;
• and
• multiplying data by the reference signal, which has been multiplexed.
