Abstract:
In the world of telecommunication, demand for 3G
mobile communication services still dominates the global market.
It continues to grow despite the introduction of new technologies
such as LTE and LTE-A. Hybrid Automatic Repeat Request
(HARQ) and Adaptive modulation and coding (AMC) are among
the key performance enhancing techniques adopted in High
Speed downlink packet access (HSDPA). Limiting the maximum
number of HARQ retransmissions in downlink is important to
save the radio resources. In this paper, we investigate the
throughput and error performance of HSDPA systems employing
HARQ and AMC, for different mobile receiver speeds.
Furthermore, the impact of turbo equalization on the
performance is also investigated. A method to obtain the optimal
value for the maximum number of HARQ retransmissions in
HSDPA is proposed.
