Power effiCienCy in wireless CommuniCations
Figure6.17 shows the power spectral density when the power
amplifier is with a MEMR = 0.45. According to Table6.3, the ACLR
for the memory polynomial technique is on average –41.8 dB and the
EVM is 0.78%, and when applying the CGMP technique these val-
ues are –55 dB and 0.71%. In this case, the improvement of around
10 dB in ACLR is achieved. According to Figure6.17, the memory
polynomial technique could not suppress the out-of-band distortion
even when the memory length increases to 20, but the CGMP tech-
nique completely reduces that effect. It should be noted that the num-
ber of iterations in ...
