:
Performance evaluation of forward error correction coding
for Rayleigh fading channels.
- Performance and analysis of product accumulate codes
on non-dispersive Rayleigh fading channels with and without
channel state information is conducted. Impressive coding
gain is achievable. Analysis focuses on
union bounding techniques and density evolution techniques
(paper).

rQuest Systems:
Automatic repeat request (ARQ) systems are widely used in wireless communications
to ensure reliable communications. In particular, type-II hybrid ARQ systems
uses incremental redundancy retransmission and is shown to be quiet
throughput efficient. The key is to design/construct good rate-compatible (RC)
codes that are both efficient and flexible.
- We investigate a capacity-approaching type-II hybrid ARQ
system: proposed a systematic scheme to construct RC-LDPC codes employing the
techniques of both extendng and puncturing, computed the thresholds of punctured
LDPC codes using Density Evolution (DE).
