TEL-KA Technologies TEL-KA

We have designed number of reusable modules which implement basic telecommunication functions. Basing on these modules, our company can quickly design and develop complex solutions for telecommuncation.
On following pages, we present examples of our solutions, grouped by method of implementation.

DSP - technologies for signal processors

    We have vast base of software modules for DSP processors, which implement algorithms of digital signal processing. Our base includes telephone modems transceiver, DTMF receivers (including mulitchannel), RF modems for short-wave frequencies (using parallel transmission), family of low speed voice codecs (1200/2400 bit/s), and measurement procedures for telepone channels quality evaluation. We have also developed DSP software modules, not directly linked to digital signal processing, like DSS1 (Q.921, Q.931) protocol implementation, or multichannel HDLC transceiver. We develop our solutions for Texas Instruments DSP series, ranging from old fixed-point TMS320C1x, through TMS320C2xx, TMS320C3x to modern TMS320C6000 series.

DSP technologies for programmable logic devices

We have designed and developed elements (modulators and demodulators) for high frequency, high speed RF devices. Due to high speed requirements of used algorithms, the modules have been implemented in FPGA devices.
In out projects we use FPGA and CPLD programmable logic devices by ALTERA.

Telecommunication modules implemented in programmable logic devices

In modern telecommunication devices, programmable logic devices are used for implementation of bit-oriented algorithims, which implementation in uProcessor oriented technique would be ineffective or costly. We have designed and developed PLD modules, which implement telecommunication devices interfaces functions.
In out projects we use FPGA and CPLD programmable logic devices by ALTERA.

Emmbeded applications

Complex telecommunication algorithms / protocols / applications are implemented as microcomputer software. For simple applications we use 8-bit uProcessors with small real-time operatng system. For more complex systems we use 32-bit RISC uProcessors with real-time operating system. For very complex devices we use PC minicomputers, running harddrive-less Linux OS.
