The topic of this Mini-Paper is the QAM modulation for LTE (long-term evolution) cellphone standard .

Unless otherwise noted, questions refer to the paper "A digital polar transmitter with DC-DC converter supporting 256-QAM WLAN and 40 MHz LTE-A carrier aggregation"

REQUIREMENTS

The required of items to be included in this mini-paper are:

Table with 2 columns: the parameter, and the parameter value (you must cite your reference for this in your paper)

Row 1: LTE 64-QAM radio center frequency in GHz (hint: see Fig. 9(c) )
Row 2: LTE 64-QAM channel bandwidth in MHz (hint: see Table I and Fig. 9(c) )
Row 3: LTE 64-QAM number of bits encoded per QAM symbol in bits/symbol (hint: see constellation )

Show the formula for a QAM signal fqam(t) from the lecture notes
Plot of measured LTE 64-QAM constellation diagram AND frequency spectrum (hint: choose correct subplots from Fig. 9 of paper ). Note: EVM (Error_vector_magnitude) refers to the error seen in the constellation

NOTE ReportTemplate: Use the Project Report Template

YOU MUST ADD CAPTIONS AND FIGURE NUMBERS TO ALL FIGURES!!
