Abstract EN
Hybrid automatic repeat request (HARQ) is used in high-speed uplink packet access (HSUPA) to increase the data rate.
Chase combining is the simplest of HARQ algorithms.
It provides a time diversity and requires a small memory.
In this paper, we propose a technique to increase the chase combining efficiency.
In this method, HARQ transmissions are seen as additional receive antennas which are jointly combined at chip-level using a space-time linear minimum square error (LMMSE).
We demonstrate that the chase combining diversity gain is considerably increased especially for high-order modulation.
