The Golden Code (GC) is a "perfect code" for the 2×2 MIMO configuration. It has already been adopted for WiMAX in the form of a Space-Frequency Block Code. The challenge with perfect codes in general and GC is in particular is the decoder. The most popular decoder for perfect codes is the Sphere Decoder (SD). But SD can become very complex as the modulation constellation and the MIMO size increase. In this paper we demonstrate how the GC can be decoded by QRM-MLD, hence paving the way for adoption of perfect codes in LTE and advanced LTE without major modifications to the transmitter and receiver.
