摘要： The invention relates generally to the field of signal encoding in a multiple input multiple output system in a wireless communication network. This invention specifically relates to a method of encoding and transmitting symbols in a rate-2 complex symbol per second per Hertz transmission system that achieves a maximum diversity of four for a four transmit antenna system and a diversity of three on a three transmit antenna system. The invention discloses a method of interleaving the complex symbols such that each interleaved symbol comprises information of at least two complex symbols where the complex symbols obtain values from a rotated constellation.

摘要： The present invention relates to a method, typically deployed on receivers deployed, for detecting a transmitted signal from a transmitter constellation by quantizing an altered signal to obtain a reduced constellation from the transmitter constellation (205), and then performing a maximum-likelihood detection scheme on the reduced constellation to obtain the transmitted signal (210). A system (120, 125) to perform the detection is also disclosed.

摘要： Methods and systems for determining a Log-Likelihood Ratio (LLR) corresponding to each bit of a symbol are provided. The symbol comprises a predefined number of bits based on a predetermined constellation. The methods and systems include expanding the predetermined constellation. The predetermined constellation comprises a plurality of constellation-points wherein each constellation-point has a unique X co-ordinate and Y co-ordinate. Also, the expanded predetermined constellation further comprises points corresponding to each combination of the X co-ordinate and the Y co-ordinate of the constellation-points. The methods and systems further include calculating the LLR corresponding to each bit of the symbol based on the expanded predetermined constellation.
