Apparatus and method for iterative detection and decoding in multiple antenna system
First Claim
1. An apparatus for performing Iterative Detection and Decoding (IDD) in a Multi-Input Multi-Output (MIMO) system, comprising:
- a detector for detecting signals received through multiple antennas to thereby generate a first soft decision value;
a decoder for decoding the first soft decision value generated in the detector to thereby generate a second soft decision value; and
a scaling unit for scaling the second soft decision value based on a scaling vector, when the second soft decision value is iteratively detected and decoded.

Abstract
Provided is an apparatus and method that can suppress deterioration in performance by scaling soft decision values for iterative detection and decoding in a Multi-Input Multi-Output (MIMO) system. The apparatus performs Iterative Detection and Decoding (IDD) and includes a detector for detecting signals received through antennas to thereby generate a first soft decision value, a decoder for decoding the first soft decision value generated in the detector to thereby produce a second soft decision value, and a scaling unit for scaling the second soft decision value based on a scaling vector, when the second soft decision value is iteratively detected and decoded.
