ARQ based half-duplex cooperative diversity protocol

Compared with [7], we focus on the same HARQ relay protocol. Unlike them, to cope with both long term and short term quasi-static channels, we choose to derive the

In this paper, we propose a novel scheme for HARQ algorithm using Orthogonal Frequency Division Multiplexing MIMO-OFDM system, the investigation is carried out for a blind

We study the synergy between coded modulation and antenna-diversity recep- tion on channels affected by slow Rician fading.. Specifically, we assess the impact of

On the other hand, next generation systems will be based mainly on CDMA, which is suited to continuous-mode transmission and (at least in its current conventional implementation [1])

In particular, we have examined the design of ` fading codes a , i.e., C/M schemes which maximize the Hamming, rather than the Euclidean, distance, the interaction of antenna

detection or joint decoding is used, i.e., arbitrarily high throughput can be obtained simply.. by increasing the transmit power of all users, as opposed to conventional CDMA

We establish the three-dimensional tradeoff between reliabil- ity (i.e. diversity), throughput (i.e., multiplexing gain), and delay (i.e., maximum number of retransmissions).
