A High-Speed Mobile OFDM Receiver LSI With an Iterative Noise-Reduction Filter to Enhance Channel Estimation

Overview This paper presents an OFDM receiver LSI with an iterative noise-reduction filter. Experimental results show that the LSI drastically improves the mobile reception performance, especially in high-speed environment. The die is fabricated with 0.18um CMOS process, including ADC, DAC and PLL. Orthogonal Frequency Division Multiplexing (OFDM) is one of the most important elements for digital TV broadcasting. This paper reports an OFDM receiver LSI with an iterative noise-reduction filter for the channel estimation.

Radioactive: Bluetooth - survival of the fastest

The opposing technology approaches are orthogonal frequency division multiplexing (OFDM) and direct sequence (DS)-UWB. The former method, backed by Intel, is more complex: it chops up the signal and sends it over multiple frequency bands.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
