[Communication] TCHFS GSM channel simulation

Description: For the simulation of a GSM transmission channel it was decided to use an information channel TCH (Traffic Channel) with high speed (Full Speed). This type of channel allows a rate of 13 Kbps. In order to create the model of TCH channel for GSM the specifications of group 3GPP were followed which are listed in [ 3GPPd ] -[3GPPg ], which they comprise of the European standard of GSM.

Description: CELP The most common Speech coding scheme is Code-Excited Linear Predictive (CELP) coding, which is used for example in the GSM standard. In CELP, the modelling is divided in two stages, a linear predictive stage that models the spectral envelope and code-book based model of the residual of the linear predictive model. -CELP The most common Speech coding scheme i s Code-Excited Linear Predictive (CELP) codin g, which is used for example in the GSM standard.

[SCM] CDMAGPRSmodem

Description: 板上资源： LM2576电源，MAX3232电平转换芯片，11.0592M有源晶振，ATMEGA128L，FM32256（铁电），滑槽式SIM卡座，40PZIF接插件，通信模块支持CM320,TC35i，MC35i，MC39i，GTM900A/B等模块。使用方法：1、不焊接M128和FM32256以及晶振，将桥接电阻R29,R30,R31焊上，就是标准串口无线MODEM，根据模块不同可以支持GPRS和CDMA，当然也可以作为GSM猫或者短信猫来使用。 2、焊上M128芯片，FM32256可以根据实际需要决定是否使用，除了支持上面的应用模式外，还能做成不需要上位机的透明传输模块，实现单片机或者一些非计算机设备无线上网传输数据的要求。-On-board resources: LM2576 power, MAX3232 chip-level conversion, 11.0592M active crystal, ATMEGA128L, FM32256 (Ferroelectric), slide-type SIM card connector, 40PZIF connectors, communications module supports CM320, TC35i, MC35i, MC39i , GTM900A/B modules. Usage: 1, non-welding as well as the M128 and FM32256 crystal will bridge resistor R29, R30, R31 welding, that is the standard serial wireless MODEM, according to the different modules can support GPRS and CDMA, of course, can be used as a cat or GSM SMS cat to use it. 2, welding on the M128 chipset, FM32256 can decide whether or not the use of actual needs, in addition to supporting the application of the above model, but also do not need to make PC transparent transmission module, the realization of single-chip or a number of non-computer equipment to transmit data wireless Internet access requirements.
