Abstract
A wireless communication device, a wireless communication system and a method to adjust transmitted signals constellation in a maximum likelihood multiple-input-multiple-output receiver by transmitting an EVM deviation value. The EVM deviation value may be added to a pre-stored error value at the receiver.

4. A method of adjusting a received signal in a multiple-input-multiple-output receivers system, the method comprising:
-
receiving a deviation of an error vector magnitude (EVM) value with a received data stream; detecting a symbol from the received data stream using a maximum likelihood detection scheme; adding the deviation EVM value to a pre-stored EVM value; and
placing the symbol on a desired constellation point. - View Dependent Claims (5, 6, 7)

8. A wireless communication device comprising:
-
a multiple-input-multiple-output (MIMO) receivers system to receive a deviation of an error vector magnitude (EVM) value with a received data stream; and a detector to detect a symbol from the received data stream using a maximum likelihood detection scheme and to add the deviation EVM value to a pre-stored EVM value and placing the symbol on a desired constellation point. - View Dependent Claims (9, 10, 11, 12, 13)

14. A wireless communication system comprising:
-
an antenna array operably coupled to a multiple-input-multiple-output (MIMO) receivers system to receive a deviation of an error vector magnitude (EVM) value with a received data stream; and a detector to detect a symbol from the received data stream using a maximum likelihood detection scheme and to add the deviation EVM value to a pre-stored EVM value in order to place the symbol on a desired constellation point. - View Dependent Claims (15, 16, 17, 18, 19, 20)
