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.
Claims20
A method comprising:
- measuring a noise level value;
- and
- transmitting the noise level value indicating a quality of the noise level in relation to a required noise level for a transmitted constellation of data streams.
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.
1 more element
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.
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.
