    Link Budget Analysis 6.6.3 Elements of a Link Budget for CDMA Standards A CDMA link budget is slightly more complicated because you must consider the spread spectrum nature of CDMA. Unlike narrowband standards such as TDMA and GSM, CDMA signals are spread over a relatively wide frequency band. Upon recep- tion, the CDMA signal is de-spread.

It’s the CDMA equivalent of sig- nal-to-noise ratio (SNR). This figure depends on the mobile’s receiver and the multipath environment. For example, the multipath delays inside a building are usually too small for a rake receiver in the mobile (or base station) to resolve and coherently combine multipath components.
