A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two graphical user interface demonstrations show some of the basic concepts of OFDM.

C语言是一门通用计算机编程语言，应用广泛。C语言的设计目标是提供一种能以简易的方式编译、处理低级存储器、产生少量的机器码以及不需要任何运行环境支持便能运行的编程语言。 C语言也很适合搭配汇编语言来使用（往往可以通过内联汇编语言或与汇编语言目标文件一起连接。对于任何一种操作系统环境，C函数的ABI（Application Binary Interface）与汇编语言的子过程（routine/procedure）的ABI一定是完全兼容的。 尽管C语言提供了许多低级处理的功能，但仍然保持着良好跨平台的特性，以一个标准规格写出的C语言程序可在许多电脑平台上进行编译，甚至包含一些嵌入式处理器（单片机或称MCU）以及超级电脑等作业平台。 二十世纪八十年代，为了避免各开发厂商用的C语言语法产生差异，由美国国家标准局为C语言订定了一套完整的国际标准语法，称为ANSI C，作为C语言的标准。二十世纪八十年代至今的有关程序开发工具，一般都支持符合ANSI C的语法

VIP+ is support software for YAMAHA RCX series robot controllers. In addition to the functions of the previously released "VIP Windows" software, VIP+ includes an easy-to-use GUI (graphical user interface). VIP+ also allows control by 2 or more controllers or access to a controller from 2 or more clients via Ethernet connection. ● With VIP+ you can: • Do offline editing of all data used on robot controllers • Operate and monitor robots connected to robot controllers • Do online editing of all data used with robot controllers • Back up and restore robot controller data ● Functions and features newly added to VIP+: • Ethernet connection to controllers • Supports data input in spreadsheet software format • Seamless backup and restoring of controller information such as point data • Syntax coloring • Data transfer between the online controller and an offline document by drag & drop • Executes online commands using a terminal window • Controller tree and document tree functions similar to Windows Explorer

The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio™ suite of DSP code development software. PurePath Studio is a highly intuitive, drag-and-drop environment that minimizes software development effort while allowing the end user to utilize the power and flexibility of the TAS3204’s digital audio processing core. TAS3204 processing capability includes speaker equalization and crossover, volume/bass/treble control, signal mixing/MUXing/splitting, delay compensation, dynamic range compression, and many other basic audio functions. Audio functions such as matrix decoding, stereo widening, surround sound virtualization and psychoacoustic bass boost are also available with either third-party or TI royalty-free algorithms. The TAS3204 contains a custom-designed, fully-programmable 135-MHz, 48-bit digital audio processor. A 76-bit accumulator ensures that the high precision necessary for quality digital audio is maintained during arithmetic operations. Four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs ensure that high quality audio is maintained through the whole signal chain as well as increasing robustness against noise sources such as TDMA interference. The TAS3204 is composed of eight functional blocks: Clocking System Digital Audio Interface Analog Audio Interface Power supply Clocks, digital PLL I2C control interface 8051 MCUcontroller Audio DSP – digital audio processing 特性 Digital Audio Processor Fully Programmable With the Graphical, Drag-and-Drop PurePath Studio™ Software Development Environment 135-MHz Operation 48-Bit Data Path With 76-Bit Accumulator Hardware Single-Cycle Multiplier (28 × 48)
