5G enhanced Mobile Broadband gains AI IP platform

PARIS — Participants at the Mobile World Congress in Barcelona next week will be plunging hip-deep into 5G use cases to discuss the myriad challenges involved, ranging from massive machine communications (NarrowBand-IoT) to ultra-low latency-required communication for connected cars. But now that the first phase of 5G standardization is complete, with the publication of 3GPP-Release 15, the biggest deal in the mobile industry is how best and how fast it can bring to customers’ equipment 5G New Radio, very-wide-bandwidth radio channels supporting data-access speeds of up to 10 Gbit per second.

In short, so-called “enhanced Mobile BroadBand (eMBB)” is everyone’s main chance right now, and that’s where a fierce 5G race will unfold in sunny Catalonia.

Among tech suppliers, Ceva Inc. will be in Barcelona, riding high with its comprehensive 5G New Radio enhanced Mobile Broadband IP Platform. Ceva devised its platform for designers of 5G smartphones, fixed wireless access and embedded devices.

Gideon Wertheizer, Ceva’s CEO, told EE Times, “Many companies — whether they plan to use 5G for the fixed wireless or embedded systems — are looking for technology they can bootstrap themselves to reach the entry point of the 5G market” as soon as possible. Calling 5G “extremely complicated technology,” Wertheizer said, “They are telling us they need something now.”

With a 5G IP platform called PentaG, Ceva is offering “a 5G modem subsystem,” Emmanuel Gresset, business development director of the wireless business unit at CEVA, told us.

The PentaG, based on a flexible architecture, has several key IP components. These include Ceva’s enhanced XC4500 DSP with 5G ISA extensions, a PentaG AI processor and vector MAC unit co-processor, a cluster of Ceva-X2 DSPs and a polar and LDPC encoder and decoder accelerator. They also come with necessary software to go with them.

Ceva brags about the flexibility of the PnetaG platform. It allows potential customers to “mix and match” any of PentaG IPs with their own design, explained Ceva CEO. “The PentaG architecture does not include a CPU,” he noted. This is deliberate, he added, “so that customers who want to use their own, legacy modem solutions can continue to do so,” while they can bring in IP blocks from PentaG to enhance their 5G offerings.

Neural networks meet 5G
Perhaps most notable in the PentaG platform is its built-in AI processor. “We are the first to use neural networks for communication,” claimed Ceva’s Gresset.

Wertheizer explained, “We found machine learning works really well when we have to figure out channel behavior in communication.” He added, “Neural networks work best when you need something you can’t predict by programming.”

Ceva has already trained the communication-related dataset on its own, offering customers patent-pending algorithms that go with the AI processor.
