Started by I'm trying to analyze a over the air RF capture. I have a RAW IQ data samples but the sample rate is 30.72Msps. The bandwidth occupied by the signal is about 10MHz...
OFDM, suppressed carriers and useful data symbol rate
Started by 5 years ago●2 replies●latest reply 5 years ago●184 viewsHello,I am studiyng #OFDM modulation and I think it's not quiet clear to me how to correctly set up the \(T_\text{ofdm} \) value when we have suppressed carriers,...
i don't know what's wrong with this #ofdm code, it gets executed but i don't get any graph.

What is the importance of adding header and tail in OFDM system?
Started by 6 years ago●4 replies●latest reply 6 years ago●323 viewsHello,I am trying to understand the functionality of header and tail in #OFDM system. I know the question sounds like a general question but I have made some search...
Semi-blind OFDM channel estimation.
Started by 6 years ago●11 replies●latest reply 6 years ago●240 viewsHello. I am currently working on a semi-blind #OFDM channel estimation. After analyzing the recorded signal(sampling frequency is known), and deriving the following...
We know that in #LTE downlink transmit uses #OFDM but in case of uplink transmit, OFDM scheme is not used. Can someone explain the reason behind this?
PAPR (peak to average power ratio)
Started by 6 years ago●11 replies●latest reply 6 years ago●2265 viewsI would like to know the relevance of peak to average power ratio and what is the ideal (or preferred) value? #OFDM
I am so confused to calculate the relationship between bandwidth and bit rate. I use #OFDM file benchmark_tx to transmit. I set the bandwidth = 10 MHz, FFT Length...
