Abstract :
This paper is focused on the evaluation of transmitter imperfections influence on single carrier and multi carrier schemes for high speed data transmission in millimeter wave band. The influence of quantization in data converters, transmitter IQ imbalances together with RF channel on the constellation diagram is evaluated. It is shown that the transceiver impairments and RF channel distort the IQ diagram in similar way for both modes, nevertheless the multi carrier mode is more suitable for the case of multipath propagation and higher user data rates. Bit-error-rate on AWGN channel is used as performance comparison criterion for foregoing imperfections.
