The e-book addresses the function of repeaters within the CDMA community, their interplay with the community and the wanted integrative layout and optimization of the repeater-embedded community. The procedure of the e-book is to boost practical comprehension of the complicated radio community, and affinity to the standards dominating the Radio source usage. basic types are constructed, and field-measured case experiences supplement the research.

Sample text

The random spreading code spreads and averages the interference sources, including other users, to become (almost) Gaussian white noise, against which the system is measured and self-adjusts. The combination of the power control and the soft handoff minimizes the interference within and between cells. The combination of these attributes forges each cell as a dynamic, "living" entity, operating as a group within the environment of other cells, and relieves the analysis from probing each user. The underlying rules stated above are simple and allow for simple monitoring, analysis, control and optimization.

In case there are already 3 pilots in the active set, and a pilot in the candidate set exceeds any of them by TCOMP they interchange locations; the weaker goes to the candidate set and the new stronger goes to the active set. T ADD Neighbor set T Active set f Candidate set Neighbor set Figure 2-3. 1 The Motivation The motivations for the third generation cellular are two-fold: technology drive and business push. The enormous success of the cellular service created a momentum for additional services, both by the technology leaders and manufacturers envisioning market saturation for the voice services, and by operators envisioning reduced profitability with increasing competition.

Most repeaters, designed for coverage extension, relay between one to three CDMA channels. The repeater can have a band filter {band repeater) or multiple channel filters {channelized repeater). The latter is structured as a heterodyne repeater, where the signal is down converted to an IF level, where channel filtering takes place, and up converted for retransmission. Channelized repeaters can be tunable to remotely or preset select the desired channels for relaying to the repeater coverage. The repeater coverage may incorporate a single lobe or multi-lobe (typically 2 or 3 lobes), materialized by a single or separate amplifiers and antennas, that may operate with different amplifiers' and antennas' gain.
