چکیده
This paper compares different multiple access schemes for broadband wireless local loop systems with a total shared capacity of 156 Mb/s per radio cell. Time Division Multiple Access (TDMA) and Orthogonal Frequency Division Multiple Access (OFDMA) are appropriate system concepts. The focus is on adaptive equalization issues for both access schemes.

The Effects of Multiple Access Schemes on Equalization for Broadband Wireless Local Loop Systems
Single carrier time division multiple access (TDMA) and orthogonal frequency division multiple access (OFDMA) are promising for broadband fixed radio access (FRA) in terms of flexibility, bandwidth-efficiency and implementation cost. Coherent detection of QPSK-symbols requires adaptive equalization. We focus on equalizer adaptation in time-variant frequency-selective FRA-channels in the presenc...

We present the following in this paper: 1) system design issues for the implementation of 51.84 Mb/s ATM-LAN and broadband access transceivers and 2) a pipelined fractionally spaced linear equalizer (FSLE) architecture. Algorithmic concerns such as signal-to-noise ratio (SNR) and bit-error rate (BER) along with VLSI constraints such as power dissipation, area, and speed were addressed in a comm...

The performance of frequency domain differentially encoded quadrature phase shift keying (FDQPSK) 26 Mb/s orthogonal frequency division multiple access (OFDMA)-systems with respect to phase noise and time-variant frequency-selective fading is analyzed. FDQPSK completely eliminates the common phase error (CPE) when used in combination with a pilot carrier. Despite its higher sensitivity to inter...

In this paper, we propose smart step closed-loop power control (SSPC) algorithm and base station assignment based on minimizing the transmitter power (BSAMTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver in the presence of frequency-selective Rayleigh fading. This receiver consists of three stages. In the first stage, with conjugate gradient (CG) adaptive ...
