The goal of Long Term Evolution (LTE) is to achieve higher data rates through more efficient transmission, and thus improving the cellular phone user experience by enabling powerful new devices. The changes required in this technology present new challenges for base station vendors and their suppliers. Supporting 4G systems efficiently requires a number of innovations in DSP design; these innovations are moving the industry toward SoC architectures to support such systems. This paper will explore how TI's new architecture enables the key features in 4G systems.

While the new multicore system on chip (SoC) signal-processing architecture announced by Texas Instruments this week at Mobile World Congress hits all the right notes with respect to what's needed in next-generation basestation designs, it rings a bit hollow given how sketchy the architectural details remain when contrasted with more 'real' announcements from the likes of Freescale. For sure, the requirements of next-generation basestations will push all architectures to their limits and beyond. Balancing lower power and lower cost with increasingly parallel, math-intensive processing to meet multiuser demands for high-data-rate data in 3GPP Long Term Evolution (LTE) Release 8 all-IP networks is not going to be easy, especially with the introduction of MIMO, beam forming, OFDMA and many other enhancements engineered to maximize spectral efficiency.
