Multiuser Ofdm-based System for Uwb Radios
نویسندگان
چکیده
In this paper we present the use of an OFDM-based scheme for ultra wideband radios in a multiuser scenario. The proposed scheme uses a technique similar to multicarrier CDMA to allow multiple users to transmit simultaneously to a single receiver. We investigate the performance of the proposed scheme in the presence of both additive white Gaussian noise and narrowband interference, with various choices for user spreading sequences.

A low complexity dynamic subcarrier and power allocation methodology for downlink communication in an OFDM-based multiuser environment is developed. The problem of maximizing overall capacity with constraints on total power consumption, bit error rate and data rate proportionality among users requiring different QOS specifications is formulated. Assuming perfect knowledge of the instantaneo...
متن کاملAvoiding WIMAX Interference on Ultra Wide Band MB-OFDM System by Cognitive Radio
This paper considers the ECMA-368 standard based on Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) as an Ultra Wideband (UWB) system in the presence of interference from an IEEE 802. 16 WiMAX systems operating at 3. 5 GHz. Simulations are conducted following the standards and adopting the IEEE 802. 15. 3a channel model CM1. This paper shows that the system fails because of the W...
متن کاملCorrelation based-Frequency offset estimation Over UWB Channels in Wireless Networks
The demand for seamless mobile connectivity and wireless internet access across the globe has been increasing. OFDM has been shown to be very efficient in wireless and wire line communication over broadband channels. Frequency offset is mismatch between transmitter frequency and receiver frequency. Frequency offset is produced by unstable receiver clock generator or Doppler Effect. OFDM systems...
متن کاملMultiuser detection for DS-CDMA UWB in the home environment
We demonstrate the effectiveness of multiuser detection for an ultra-wideband (UWB) pulse based direct sequence spread spectrum system using code division multiple access. Extensive simulations were run using channel soundings of the 2–8 GHz band collected in a residential setting and characterized by a high level of multipath fragmentation. We show that the adaptive minimum mean square error (...
