19 Oct 2007TL;DR: In this article, a multiple-input, multiple-output (MEMO) communication system is configured to utilize a variable slot structure, and the base station is operative to determine mobilities for respective ones of the terminals, to arrange the terminals into groups based on the determined mobilities, and to utilize at least first and second different slot structures for communicating with the terminals of at least respective first-and second ones of groups.
Abstract: A multiple-input, multiple-output (MEMO) communication system is configured to utilize a variable slot structure. The system includes multiple terminals and at least one base station configured to communicate with the terminals. The base station is operative to determine mobilities for respective ones of the terminals, to arrange the terminals into groups based on the determined mobilities, and to utilize at least first and second different slot structures for communicating with the terminals of at least respective first and second ones of the groups. The system may be, for example, a multi-user MIMO system in which the multiple terminals comprise autonomous single-antenna terminals.

TL;DR: Insight is presented into the essential elements of the DVB-T demodulation core design, the design methodology, and project management and the underlying signal processing algorithms, the bit accurate model, and register transfer level code.
Abstract: The terrestrial digital video broadcast (DVB-T) system, specified in the ETSI 300–744 standard, is currently the most popular digital television system with more than 120 million receivers deployed globally in integrated television sets, set-top boxes, in-car modules, universal serial bus (USB) sticks, and personal computer (PC) cards. A provider of multimedia application specific integrated circuits (ASICs) in Asia required a DVB-T demodulation core as part of its strategy to broaden its stake in this growing market. To meet this challenge, Bell Labs partnered with Cambridge Industries Group, China, to form an international team to design and implement the underlying multimode orthogonal frequency division multiplexing (OFDM)–based receiver. This paper presents insight into the essential elements of the system design, the design methodology, and project management and describes the underlying signal processing algorithms, the bit accurate model, and register transfer level code. It is demonstrated how close collaboration between Bell Labs and selected global partners can yield added value to Alcatel-Lucent. © 2007 Alcatel-Lucent.
