| | PDF (2554 KB) | HTML

We focus on the design of distributed Luby transform (DLT) codes for erasure networks with multiple sources and multiple relays, communicating to a single destination. The erasure floor performance of DLT codes improves with the maximum degree of the relay-degree distribution. However, for conventional DLT codes, the maximum degree is upper bounded by the number of sources. An additional constrain... View full abstract»

The dynamic spectrum access (DSA) among multiple heterogeneous primary spectrum owners (POs) and secondary users (SUs) in recall-based cognitive radio networks is investigated in this paper. In our framework, SUs demand a different amount of spectrum for their transmissions. Each PO provides a portion of radio resources for leasing and also offers its own primary users (PUs) a certain degree of qu... View full abstract»

Adapting the power of secondary users (SUs) while adhering to constraints on the interference caused to primary receivers (PRxs) is a critical issue in underlay cognitive radio (CR). This adaptation is driven by the interference and transmit power constraints imposed on the secondary transmitter (STx). Its performance also depends on the quality of channel state information (CSI) available at the ... View full abstract»

| | PDF (1112 KB) | HTML

The problem of designing an optimal vector quantizer when there is access to the noise-free source has been well studied over the past five decades. However, in many real-world situations, the source output may be corrupted by some additive noise. In this case, we only have access to a noisy version of the data, but we expect a designed quantizer to minimize the distortion with respect to the clea... View full abstract»
