Voice over IP application on TMS320C6701 EVM DSP Board
نویسندگان
چکیده
Development of a low bit-rate voice over IP application is described. A speech coding algorithm is constructed and implemented on a digital signal processor (DSP). The algorithm is based on a sub-band mixed excitation LPC vocoder structure and operates at a rate of 2000 bits per second. Implementation is done on two TMS320C6701 floating point DSP’s each connected to a PC. On the PC, a graphical user interface (GUI) controls the data flow over the IP network. The application runs in full duplex and supports poor to fair sound quality depending on the used recording equipment.

Software Radio Implementation of a Smart Antenna System on Digital Signal Processors for cdma2000
This paper presents a software defined radio (SDR) implementation based on programmable digital signal processors (DSP) for smart antenna systems (SAS). We evaluate adaptive beamforming algorithms, namely nonblind-type least mean square (LMS) and blind-type constant modulus (CM) using TI TMS320C6000 high performance DSPs for cdma2000 reverse link. Adaptive beamformers are implemented using TI c...

In this work, we implemented the Click IP Router Kernel in C language provided by Scott Webber et al. for two VLIW processors designed for DSP purpose, namely the Philips Trimedia TM1300 processor and Texas Instrument TMS320C6701 processor. The performance of these processors are compared with those of three other processors, ARM SA-110, HPL-PD EPIC, and Intel IXP1200 [1]. Ways of further perfo...
متن کاملA Real Time Singing Voice Removal System Using DSP and Multichannel Audio Interface
Separating technique for singing voice from music accompaniment is very useful in original sound type Karaoke instrument. We propose a real-time system to separate singing voice from music accompaniment for stereo recordings. Proposed algorithm consists of two stages. The first stage is a spectral change detector. The last stage is a selective vocal separation in frequency bins. Our system cons...
متن کاملAn Adaptive Filter for Radar Clutter Suppression Based on the TMS320C6701 DSP
In the paper an adaptive filter of witch characteristics track changes of the observations conditions in real-time with use of the enhanced TMS320C6701 Evaluation Module board is described. This filter can be used to cancel narrow bandwidth interferences with unknown power spectral density from a received radar signal. This real-time process requires fast A/D converter. We achieved this by usin...
