Abstract :
In this paper, we introduce two packet combining schemes with low complexity minimum mean square error (MMSE) turbo equalization for single user multi-code CDMA transmission over a broadband multiple input multiple output (MIMO) channel. The first scheme considers each transmission as an additional set of virtual receive antennas and combines multiple transmissions using a frequency domain chip level turbo equalizer. The second scheme performs frequency domain turbo equalization separately for each transmission then combines filter outputs. A comparative study in terms of performance and complexity is conducted to show the great potential of packet combining with integrated turbo equalization.
