Matlab信道建模相当好的文章! In this paper, a MATLAB based approach for mobile radio channels modeling is presented. Specifically, the paper introduces the basic concepts for modeling flat fading channels in MATLAB by means of user-defined m-files.
General Packet Radio Service (GPRS) is a mobile data service available to users of GSM mobile phones. It is often described as "2.5G", that is, a technology between the second (2G) and third (3G) generations of mobile telephony. It provides moderate

The Mobile Communications Handbook covers the entire field - from principles of analog and digital communications to cordless telephones, wireless local area networks (LANs), and international technology standards. The amazing scope of the handbook
The STM3210B-EVAL is an evaluation board for STMicroelectronic’s ARMTM Cortex-M3 core-based STM32F10x 128K microcontrollers. It is designed as a complete development environment for the STM32F10x microcontrollers with full speed USB2.0, CAN2.0A/B co
Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center, left front, right rear
6.1 MS shared protection rings MS shared protection rings can be categorized into two types: two-fibre and four-fibre. The ring APS protocol accommodates both types. For MS shared protection rings, the working channels carry the normal traffic signa
A standard on low bit rate coding for mono or stereo audio signals was established by MPEG-1 Audio in ISO/IEC 11172-3. This standard is applicable for carrying of high quality digital audio signals associated with or without picture information on s
In an OFDM scheme, a large number of orthogonal, overlapping, narrow band sub-channels or subcarriers, transmitted in parallel, divide the available transmission bandwidth. The separation of the subcarriers is theoretically minimal such that there i
