Node B Receiver Transmitter Implementation

In Chapters 2 and 3 we discussed the suitability of the digitally sampled IF superhet
and the direct conversion receiver architecture for handset implementation. We concluded
that either configuration was capable of meeting the handset specification but
that longer term, the DCR (or near-zero IF) could show a reduction in component
count—especially in multistandard environments—although problems of DC offsets
required considerable DSP power (baseband compensation).
