Infotech Oulu Lecture Series Lecturer: Associate Professor Henk Wymeersch, Chalmers University of Technology, Sweden Date: January 30, 2015Time: 14:15 - 15:0xRoom: TS128 (Tietotalo 1) Abstract: Ultra-wide bandwidth (UWB) systems allow for accurate positioning in environments where global navigation satellite systems may fail, especially when complemented with cooperative processing. While cooperative UWB algorithms have led to centimeter-level accuracies, the communication overhead is often neglected. In this talk, we quantify how positioning accuracy and medium access delay trade off and derive an asymptotic scaling of accuracy and delay. Surprisingly, our study indicates that in some conditions, standard cooperation offers the worst possible trade-off. This is also an IEEE chapter event, see http://www.cwc.oulu.fi/IEEE_COM19/.
A Soft Network Coded Multilevel Forwarding Scheme for Multiple Access Relay Systems & Index Coding for Broadcast Channel with Side Information
Infotech Oulu Lecture Series Date: January 21, 2015Time: 10-12Room: TS127 A Soft Network Coded Multilevel Forwarding Scheme for Multiple Access Relay Systems Lecturer: Dr. Nalin Jayakody, University of Tartu, Estonia Abstract Many wireless relay protocols have been proposed in the literature to reap the benefits promised by cooperative wireless communication. The two most frequently used relaying protocols are decode-and-forward (DF) and amplify and forward (AF). The main performance degradation in a DF protocol arises from error propagation during retransmission when decoding errors occur at the relay in the low SNR regime of the source-relay channel. In the AF relay protocol, the signal received by the relay is amplified and re-transmitted to the destination. Different amplifying factors may be used. In contrast to DF, the AF protocol suffers from noise amplification, but AF precludes premature decisions and thus preserves the soft information content of the received signal. DF lacks the main advantages of AF and vice versa. One way of avoiding the error propagation and noise amplification is to calculate and forward the corresponding soft information instead of making a premature decision based on the transmitted information symbols at the relay. Soft information indicates the reliabilities or probabilities of the underlying symbols. We refer to such a protocol as soft information relaying (SIR). In this talk we propose a novel technique of multilevel threshold based soft quantization (MLT-SQ) scheme for a multiple access relay system (MARS). The scheme is suitable for systems using binary phase-shift keying (BPSK) and network coding at the relay. In the proposed MLT-SQ protocol, the relay evaluates the reliabilities, expressed as log-likelihood ratios (LLRs), of the received signals from the two sources. It then computes the LLRs of the network-coded packet and quantizes these using a set of optimized multilevel thresholds, forwarding the resulting “quantized soft symbols” to the destination. We provide the derivation for the bit error rate (BER) at the destination, based on which we optimize the multilevel thresholds to minimize the BER. Simulation results are provided for the proposed MLT-SQ system, both without coding and for the case where low-density parity-check (LDPC) coding is employed. The proposed system achieves full diversity order. The performance of our system is superior in terms of BER when compared to other relevant competing schemes.
