Path-Based Error Coverage Prediction
We present an analytical technique that uses fault injection data for estimating the coverage of concurrent error detection mechanisms in microprocessors. A major problem in such estimations is that the coverage depends on the program executed by the microprocessor as well as the input sequence to the program. We propose a method that predicts the error coverage for a specified input sequence b...
متن کاملReception of OFDM signals with an array antenna in a SFN environment
In the OFDM SFN system where the received signal from the main broadcast station is rebroadcasted at the relay station, the area where the delay spread of the received signal is longer than the guard interval length increases as compared to the SFN system where the signals are transmitted at the same time both from the main station and from the relay station. If the channel delay spread is long...
متن کاملPerformance of Multicast MISO-OFDM Systems
In this paper, we evaluate the performance of multicast OFDM systems with single and multiple transmit antennas. We have shown that it is possible to increase the data rate of multicast OFDM systems by selecting the users with good channel for each subcarrier. For the single transmit antenna case, the resource allocation has been applied using the two-step algorithm where subcarrier allocation ...
متن کاملImproving Multicast Stability in Mobile Multicast Scheme Using Motion Prediction
Stability is an important issue in multicast, especially in mobile environment where joining and leaving behaviors occur much more frequently. In this paper, we propose a scheme to improve the multicast stability by the use of motion prediction. The mobile node (MN) predicts the staying time before entering the new network, if the time is long enough, it will ask the new network to join the mul...
متن کاملAdaptive Rate Control for Multi-Antenna Multicast in OFDM Systems
We propose two rate control schemes for multi-antenna multicast in OFDM systems, which aim to maximize the minimum average rate over all users in a multicast group. In our system, we do not require all multicast users to successfully recover the signals received on each subcarrier. In contrast, we allow certain loss for multicast users, such that the multicast transmission rate can be increased...
