Implement Of Physical Layer Of HSPA And HSPA+in Td-Scdma Terminal Protocol Analysis Tester

TD-SCDMA, a home-grown standard for the third generation mobile communications, is already mature and ready for commercial deployment. In order to ensure the healthy development of TD industrial chain, protocol analysis for mobile terminal chip is indispensable. The work is from "TD-SCDMA terminal protocol analysis tester".The protocol analysis function for Release4of TD-SCDMA standard has already been completed. Author upgraded physical layer software to make the product support protocol analysis for Release5,7,8of TD-SCDMA standard.HSPA and HSPA+are mainly introduced in Release5,7and8of TD-SCDMA standard. HSDPA channels(HS-SCCH, HS-PDSCH and HS-SICH) and HSUPA channels(E-RUCCH, E-AGCH, E-PUCH and E-HICH) are brought in HSPA and HSPA+. The physical channels not only continue to follow Release4of TD-SCDMA standard, but also add new physical layer technologies such as HARQ, constellation rearrangement,16/64QAM, etc. The implement of these technologies are discussed in detail in chapter3. The implement of physical layer for HSUPA maximum rate is the difficulty and author solved the problem by designing framework and optimizing code, which are also discussed in chapter3.The thesis discusses verification of physical layer in "TD-SCDMA terminal protocol analysis tester" in chapter4. Terminal protocol analysis for HSDPA and HSUPA was tested and terminal log proved the HSPA function for physical layer. Author also carried a protocol analysis for HSUPA maximum rate and gave the reason for rate bottleneck through instrument log. Author only verified physical layer in HSPA+through MATLAB simulation for the reason that HSPA+terminals are inaccessible.The thesis has been applied to "TD-SCDMA terminal protocol analysis tester", and recognized by international famous chip manufacturers.
