Precoded and Vector OFDM Robust to Channel Spectral Nulls and With Reduced Cyclic Prefix Length in Single Transmit Antenna Systems
White Paper It also proposes size K x 1 vector OFDM (VOFDM) systems that reduce the cyclic prefix length by K times compared to the conventional OFDM systems. The performance of orthogonal frequency-division multiplexing (OFDM) systems may be degraded when... [21 Oct 2004]
Channel Estimation for OFDM Systems in Case of Insufficient Guard Interval Length
White Paper This paper presents a novel method used to channel estimation for OFDM systems in case of insufficient guard interval length. This method suppresses additive noise and interference components by averaging the estimated channel coefficients in the... [10 Sep 2007]
The Length and Cost of Banking Crises
White Paper This paper reviews how recent studies of banking crises differ with regard to the dating, length, and costs of the crises. The data allow an examination of the relation between perceived crisis length, as an index of delay in taking actions to... [24 Feb 2004]
On the Construction of Variable-Input-Length Ciphers
White Paper Whereas a block cipher enciphers messages of some one particular length (the blocklength), a variable-input-length cipher takes messages of varying (and preferably arbitrary) lengths. Still, the length of the ciphertext must equal the length of the... [24 Feb 2004]
A Novel OFDM Transmission Scheme With Length-Adaptive Cyclic Prefix
White Paper Conventional OFDM transmission system uses a fixed-length Cyclic Prefix to counteract Inter-Symbol Interferences (ISI) caused by channel delay spreading under wireless mobile environment. This may cause considerable performance deterioration when... [01 Nov 2004]
Towards an Erlang-Like Formula for the Performance Evaluation of GPRS/EDGE Networks With Finite-Length Sessions
White Paper After a preliminary focus on infinite-length sessions, which provide a simpler analytical framework, the paper includes finite-length sessions and studies their specific effects. The focus of this paper is on a simple yet important objective: to... [21 Nov 2005]
Variable-Length Encoding of DGPS Corrections for Mobile Devices Via the Internet
White Paper This paper presents a technique for encoding differential corrections for distribution to mobile devices via the Internet that combines variable length entropy coding and keyframe-based differential coding techniques to reduce the data bandwidth... [28 Nov 2005]

Comparison of Width-wise and Length-wise Language Model Compression
White Paper In this paper we investigate the extent to which Katz back-off language models can be compressed through a combination of parameter quantization (width-wise compression) and parameter pruning length-wise compression) methods while preserving... [24 Feb 2004]
A Joint Channel and Channel Length Estimation Algorithm for MIMO-OFDM
White Paper Few, however, have addressed the practical problem of estimating the instantaneous channel length. This paper proposes a method for jointly estimating the channel and instantaneous channel length. The recent interest in coherently detected MIMO... [26 Jul 2005]
TCP Capture Avoidance in Wireless Networks Based on Path Length and Path Density
White Paper This paper proposes a distributed ingress throttling scheme for wireless networks based on path length and path density such that TCP fairness is guaranteed. To this end the paper introduces a model for the sustainable load permitted in the MAC... [26 Dec 2007]
