— Spectrum sensing is a key enabling functionality in cognitive radio (CR) networks, where the CRs act as secondary users that opportunistically access free frequency bands. Due ...
Abstract— The use of multi-user detection (MUD) in a cooperative CDMA network is investigated for the uplink in synchronous CDMA systems. Suppose that, at any instant in time, pa...
--- In this paper, a novel third-order Phase Lock Loop (PLL) is proposed for the timing recovery in MIMO-OFDM systems. It differentiates from conventional timing recovery algorithm...
In a Wyner-Ziv video coding system based on turbo codes, parity bits are generated for a Wyner-Ziv frame and transmitted to the decoder. In this context of distributed source codi...
—This paper presents a new context modeling technique for arithmetic coding of DCT coefficients in video compression. A key feature of the new technique is the inclusion of all p...
