This paper presents a new type of hybrid ARQ scheme for error control in data communication systems. The new scheme is based on the concept that the parity-check digits for error correction are sent to the receiver only when they are needed. Normally, data blocks with some parity-check bits for error detection are transmitted. When a data block D is detected in errors, the retransmissions are not simply repetitions of D , but alternate repetitions of a parity block P(D) and D . The parity block…

An analysis of the effectiveness of hybrid transmission schemes
It is shown that a probability of undetected error of less than 10-9 error/bit, can be achieved by correcting only a few errors while retaining a reasonable throughput and a very low retransmission rate.
Errors and error control
It is shown qualitatively that automatic-repeat-request (ARQ) systems are inherently better suited to the task than forward-error-control (FEC) systems.
An Efficient Selective-Repeat ARQ Scheme for Satellite Channels and Its Throughput Analysis
Both analytical and simulation results show that it significantly outperforms the go-back- N ARQ scheme, particularly for channels with large roundtrip delay and high data rate, and provides high throughput efficiency over a wide range of bit error rates.

The Analysis of Some Selective-Repeat ARQ Schemes with Finite Receiver Buffer
Analyzing a class of mixed-mode ARQ protocol models which incorporate a selectiverepeat mode with finite receiver buffer shows that it is desirable for best throughput performance in practical systems that at least the first retransmission of a block following an error should be in the selective-repeat mode to obtain superior performance over GoBack N schemes.
