Turbo decoding offers outstanding error correcting capabilities, that will be used in wireless applications like the Universal Mobile Telecom Standard[4] (UMTS). However, the algorithm is very computational intensive, and therefore an implementation on a general purpose programmable DSP results in a power consumption which reduces the applicability of turbo(More)
The current trend in the consumer devices and communication service provider market is the integration of different communication standards within a single device (e.g. GSM phone with Bluetooth, WLAN and infrared interface) requiring tight integration of mobile broadcast, networking and cellular technologies within one product. Channel decoder is(More)
This paper compares selected digital signal processing algorithms on a variety of computing platforms in terms of achievable performance and cost. The experiments were carried out on a standard PC platform, DSP, a RISC mi-crocontroller and on Xilinx XC4013XL FPGA. Our results confirm that general purpose microprocessors are not well suited to these tasks.(More)
