2002 1849 Performance of Blind and Group-Blind Multiuser Detectors Anders Høst-Madsen‚ Member‚ IEEE‚ and Xiaodong Wang‚ Member‚ IEEE Abstract—In blind (or group-blind) linear multiuser detection‚ the detector is estimated from the received signals‚ with the prior knowledge of only the signature waveform of the desired user (or the signature waveforms of some but not all users). The performance of a number of such estimated linear detectors‚ including the direct-matrix-inversion (DMI) blind

Signal Theory Introduction- In this report I will be writing about Signal Theory and all of its aspects‚ this involves talking about how data is transferred over a network‚ what a packet is and what information it contains‚ asynchronous and synchronous transmission‚ errors that data may encounter and what protocols are in place to avoid this from happening. Digital Signalling Methods- When data is sent over a network‚ it can either be through a wired or a wireless technology. The data is

Twisted-pair cable is used in telephone lines for voice and data communications. * Coaxial cable has the following layers (starting from the center): a metallic rod-shaped inner conductor‚ an insulator covering the rod‚ a metallic outer conductor (shield)‚ an insulator covering the shield‚ and a plastic cover. Coaxial cable can carry signals of higher frequency ranges than twisted-pair cable. Coaxial cable is used in cable TV networks and traditional

Unit 1. Assignment 1. Voice vs. Data NT1310 July 24‚ 2013 A cell phone is a two-way radio that sends and receives radio signals to and from cell site base stations. When a person talks on a cellular phone‚ the voice message gets converted into radio waves. The radio waves travel through air until they reach a base station close by. The base station sends the call across the communication network after which the call reaches the intended receive Landline telephones use voice transmission where

Wireless Signals Michael Rubendall IT/242 February 25th 2013 Benny Lane Wireless Signals Wireless signals are all around us as we walk or drive around the city or town where we live. The four types of wireless technologies that are out there are Wi-Fi‚ Cellular‚ Bluetooth‚ and WiMAX. We will be looking at these types of wireless technologies a little more in depth‚ where are they most commonly used‚ and how they differ from one another. The first wireless technology that we

Distinguish between primary data and secondary data? Primary data is the data that is collected first hand from the original source for the purpose of making statistical inference while secondary data is the data that is collected by the method of abstraction and is used to make statistical inference by using primary data already collected by an investigator. Primary data is collected by Identifying population of interest choosing sample analyse sample information draw inference from
