TC1700: Turbo decoder Core for HSPA+, LTE and WiMAX

TC1700 is a turbo decoder that supports three PHY layer specifications:

• 3GPP-HSPA
• 3GPP-LTE
• WiMAX IEEE802.16e

The Core can be implemented in Base station or CPE receivers. The Core uses a unique architecture that reduces by more than 50 % the silicon area when compared to separate single-mode Cores, with no restrictions on the flexibility and features set. The Core is based on our robust and silicon-proven architecture that has been adopted by leading 4G system-on-chip manufacturers. The corresponding encoder Cores are also available with similar functional coverage.
