OutlinevMultiple access/channel measurement guidelinesvCurrent 1G and 2G technologyvWhat is Third Generation?vWCDMA featuresv cdma2000 featuresvWCDMA and cdma2000 contrastedvSummary
May 28-June1, 2001 R. Z. Ziemer, Colorado Springs, CO 3
Rules for Efficient Multiple Access vThree immutable lawsvKnow the channelvMinimize interference to othersvMitigate interference received from others
vRequirements of wireless multiple accessvChannel measurementvChannel control and modificationvMultiple user channel isolation
May 28-June1, 2001 R. Z. Ziemer, Colorado Springs, CO 4
Channel Measurement Guidelinesv Wider the bandwidth = better the measurementv Limitations on this rule
v Regulatory (indoor path isolation = 10 ns delay resolution)v Complexity (combining more paths = more hardware)v Physical limitations (splitting energy over more paths = increasingly
inaccurate parameter measurements)
v Measure at frequency > rate of change of channelv No other users: good receiver attempts to put together all
received multipath components coherentlyv Other users present: Optimum = multiuser detection;
suboptimum = power control; minimize near-far problem

Why CDMA?v Higher capacityv Improved performance in multipath by diversityv Lower mobile transmit power = longer battery lifev Power controlv Variable transmission rate with voice activity detection
v Allows soft handoffv Sectorization gainv High peak data rates can be accommodatedv Combats other-user interference = lower reuse factors

Notes:1) For fixed chip rate, desired information
rate determines length of spreadingsequence and therefore processing gain.
2) When a specific code is used, no other code on the path from that code to the root and or on the subtree beneath that code may be used.
3) All the codes at any depth into the treeare the set of Walsh Sequences.
4) Code phase is synchronous withinformation symbols.
5) FDD UL processing gain between 256 and 4FDD DL processing gain between 512 and 4TDD UL/DL processing gain between 16 and 1
6) Multicode used only for SF = 4
