For a 50MHz bandwidth and carrier spacing of 1.25KHz, how many maximum number of sub carriers are possible?
Explain how the use of OFDM in modern communication systems has enabled efficient data transmission over wireless channels with different channel characteristics, and what is the role of IFFT in OFDM signal generation?
Why is the addition of zero samples done on both side of the sequence and not just directly at one end of the sequence?
What is the relationship between the number of subcarriers and the IFFT size in orthogonal frequency-division multiplexing (OFDM) systems?
Suppose a wireless system uses an OFDM-based uplink transmission scheme, where the IFFT size is 2048 and the subcarrier spacing is 15 kHz. The system supports multiple users, with each user allocated a certain number of subcarriers for ...Read more
What are the challenges associated with PRACH upsampling and downsampling, and how can they be addressed?
In converting the ZC-sequence frequency domain samples to time domain by using IFFT in uplink transmission of PRACH signal, the IFFT is not taken over entire long length samples to avoid complexity of IFFT and FFT blocks. Instead another simple ...Read more
A wireless communication system uses OFDM with 64 subcarriers and a 512-point IFFT for modulation. The system operates in a frequency band of 20 MHz. The modulation scheme used is QPSK (Quadrature Phase Shift Keying), where each symbol carries 2 ...Read more
