Wideband OFDM receiver using split spectrum processing

Blind OFDM Channel Estimation Using Receiver Diversity

In this paper we exploit receiver diversity for blind channel estimation for OFDM systems with cyclic prefix. The developed channel estimation algorithm has the following advantages compared with existing blind methods: a) It is data efficient — the proposed algorithm can be implemented using a single OFDM block; b) It is computationally efficient — only a single singular value decomposition is...

Hyper-wideband Ofdm System

OFDM Receiver Design

Othogonal Frequency Division Multiplex (OFDM) has gained considerable attention in recent years. It has been adopted for various standards include the 802.11a wireless LAN standard. In this project, we implemented an OFDM receiver based 802.11a standard. Furthermore, since spatial diversity is the ultimate way to increase system capacity in bandwidth-cautious wireless applications, the SVD ante...

A Compact Ultra-Wideband Bandpass Filter with Sharp-Rejection using Complementary Split Ring Resonators

A compact and sharp-rejection ultra-wideband (UWB) microstrip band-pass filter (BPF) is developed using of left handed metamaterials realized by complementary split ring resonator (CSRR). Moreover, proposed structure consists of two doublets parallel coupling gaps at each side of a microstrip ring. In comparison with some other filters, this structure shows a significantly wider passband due to...

Performance of ultra-wideband correlator receiver using Gaussian monocycles

This paper investigates the performance of UltraWideband (UWB) correlator receivers for Gaussian monocycles under the condition of equal mean power and provides constructive reference to the selection of pulses. Several channel situations are examined including ideal single user AWGN channel, non-ideal synchronous, multipath fading and multiple access interference. Both numerical and analytical...
