“…One practical method for such recovery is through an automatic repeat request (ARQ) mechanism [54], [134], [155] where the receiver (through a feedback mechanism) notifies the transmitter that the packet was in error. Therefore, there can be several recovery techniques when a packet error is detected, depending on the possible actions that either the transmitter or the receiver may take (which basically pertain to hybrid ARQ protocols [171]).…”

“…; ' À 1Þ; must be available in the buffer to form the updated version of the combined packet % Z Z ð'Þ : The receiver operation of this ARQ scheme is shown in Figure 3. The average diversity combining proposed in Reference [10] and used here in the HARQ-II scheme is a method for combining the received packet with its predecessors until the resulting combined packet can be reliably decoded. The throughput and reliability performance can be improved through the use of this packet combining.…”

SUMMARYThis paper is concerned with a direct sequence spread spectrum system making use of automatic repeat request (ARQ) schemes and operating in the presence of narrow-band (NB) interference and additive white Gaussian noise. In this study, we evaluate the system's throughput efficiency when a suppression filter is employed at the receiver to mitigate the effect of NB interference. Specifically, we investigate how the performance is influenced by various parameters such as the number of filter taps, processing gain, type of interference, and the signal power-to-interference power ratio. The simulation results show that using the suppression filter significantly improves the throughput performance of the hybrid ARQ schemes in the presence of NB interference.

“…Diversity-combining systems are generally suboptimal with respect to code-combining systems, but are simpler to implement. These schemes are represented by the work of Sindhu [90], Benelli [98], [99], Metzner [100], [101], and Harvey and Wicker [102].…”

Abstract-An overview of the many practical applications of channel coding theory in the past 50 years is presented. The following application areas are included: deep space communication, satellite communication, data transmission, data storage, mobile communication, file transfer, and digital audio/video transmission. Examples, both historical and current, are given that typify the different approaches used in each application area. Although no attempt is made to be comprehensive in our coverage, the examples chosen clearly illustrate the richness, variety, and importance of error-control coding methods in modern digital applications.
