Detection method and apparatus for a multi-stream MIMO

A computer program embodied on a computer readable medium, the computer program comprising program code for controlling a processor to execute a method comprising:

• receiving multiple spatial signal streams from a multiple-input multiple output channel;
• and
• pre-ordering said multiple received spatial signal streams based on modulation alphabets of said received spatial signal streams prior to performing a QR Decomposition-M detection.
