Efficient Inner Receiver Design for OFDM-Based WLAN Systems: Algorithm and Architecture

Autor: Eckhard Grass, Ulrich Jagdhold, Milos Krstic, Rolf Kraemer, Koushik Maharatna, Alfonso Troya

Publikováno v: IEEE Transactions on Wireless Communications. 6:1374-1385

In this article we propose a complete solution for the so-called inner receiver of an OFDM-WLAN system based on the IEEE 802.11a standard. We concentrate our investigations on three key components forming the inner receiver namely, the synchronizer,

Low-power VLSI implementation of the inner receiver for OFDM-based WLAN systems

Autor: Koushik Maharatna, Milos Krstic, Alfonso Troya, Ulrich Jagdhold, Eckhard Grass, Rolf Kraemer

In this paper, we propose low-power designs for the synchronizer and channel estimator units of the Inner Receiver in wireless local area network systems. The objective of the work is the optimization, with respect to power, area, and latency, of bot

On the Implementation of a Low-Power IEEE 802.11a Compliant Viterbi Decoder

Autor: Milos Krstic, Koushik Maharatna, Alfonso Troya, Eckhard Grass

Publikováno v: VLSI Design

This article describes a standard cell based novel implementation of a low-power Viterbi decoder (VD) targeted for the IEEE 802.11a wireless LAN system. Multiple clock rates have been used to reduce the power consumption and the inherent bandwidth mi

Simplified residual phase correction mechanism for the IEEE 802.11a standard

Autor: Alfonso Troya, Milos Krstic, Koushik Maharatna

Publikováno v: Scopus-Elsevier

It is of common use in OFDM transmission to define some of the sub-carriers as pilots. These sub-carriers contain information, which is known a priori at the receiver and are typically used for channel estimation. In the special case of the IEEE 802.

Virtually scaling-free adaptive CORDIC rotator

Autor: Swapna Banerjee, Alfonso Troya, Eckhard Grass, Koushik Maharatna

Publikováno v: IEE Proceedings - Computers and Digital Techniques. 151:448

In this article we propose a novel CORDIC rotator algorithm that eliminates the problems of scale factor compensation and limited range of convergence associated with the classical CORDIC algorithm. In our scheme, depending on the target angle or the
