Concepts Covered in this Series 3x:
Bandwidth scalability from 1G 2G 3G and 4G
How is severe ISI introduced in wireless frequency selective fading channel?
Delay Spread
Flat Fading Channel
How is ISI reduced in wireless frequency selective fading channel?
Single Carrier system
Up Conversion
Down Conversion
Design of FDM and it's disadvantages
Why is Guard band required in FDM??
Design of OFDM and block diagram of OFDM
Difference between FDM and OFDM
Shifting the subcarriers by half bandwidth so that the entire baseband is centered at DC
Choosing FFT size in OFDM for faster processing
Null subcarriers at the bandwidth edge in OFDM to cater filter roll-off
Sampling frequency calculations and it's advantage to cater filter roll-off
Advantages of shifting the signal to center around DC - Avoids in designing wide band filters
4G OFDM Grid or Resource Grid (3GPP TS 36.211 14.2v section 5.2.1)
What is One OFDM Symbol vs one IQ
What is RB
RE (Resource Element) Mapping
Cyclic Prefix requirements (CP addition block) design
Does OFDM increase data rate when compared to single carrier system? | If so, how ?
BW, FFT Size, CP, Guard Band, Fs - Design of various parameters for OFDM
