T1: A Survival Guide - Timing, Clocking, And Synchronization In The T-Carrier System
White Papers Three major types of timing are used on networks: asynchronous, synchronous, and plesiochronous. The three differ in how they distribute timing information through the network. Asynchronous systems do not share or exchange timing information.

Timing Synchronization In High Mobility OFDM Systems
White Papers The performance of OFDM systems, however, is sensitive to the performance of the timing synchronizer and channel estimator (in this paper, timing synchronization refers to the correct detection of the start of an OFDM symbol).

Symbol Timing For Multiple Antenna OFDM Systems
White Papers Accurate symbol timing in Multiple-Input Multiple-Output (MIMO) OFDM systems allows for Guard-Intervals (GIs), which are short compared to the channel's rms delay spread. This paper proposes different timing approaches for MIMO OFDM systems, which...

Data-Aided Timing Offset Estimation For Frequency Selective Fading Channels
White Papers A novel algorithm for Timing offset estimation is proposed in this paper for GSM and GPRS handsets, especially for multi-path channels with large delay-spread. The timing offset leads to errors in the channel response estimation with a consequent...
