An Improved HARQ Scheme with Unlimited Retransmission Number
Xin Cao · Telecommunication Engineering · 2005
In fading and shadowing channels,error control techniques are used for the reliable transmission.As a combination of forward error correction and automatic repeat request(ARQ),Hybrid ARQ(HARQ) protocol provides both of the advantages.In this paper,an improved HARQ scheme using RCPT(Rate Compatible Punctured Turbo) codes is compared with traditional RCPT-HARQ scheme in fast and slow Rayleigh fading channels.Simulation results show that the proposed scheme has high throughput in slow Rayleigh fading channels.
