Hi, Can anyone explain the USIM authentication process in 5G in simple words?

How does decimation help in reducing the complexity of the receiver in PRACH?

How do you determine the appropriate interpolation factor for a given signal?

How does decimation affect the accuracy of a digital filter?

how does the Polyphase filter work?

How to increase the sampling rate of the given signal by a factor of 5.125.

Explain how the decimation helps in the detection of PRACH? What happens if the decimation step is skipped while detecting the PRACH?

Explain why decimation is time variant by giving an example?

What are some of the trade-offs involved in using decimation and interpolation in 5G PRACH, and how can these be optimized ?

What is the concept of aliasing in interpolation and how can it be avoided?

Let’s assume the incoming signal is sampled at the rate of 500 kHz and required sampling rate of the signal is 10 kHz. Therefore we need to decimate the signal by a factor of 100. Let’s assume the baseband frequency of ...Read more

How does the choice of decimation technique affect the signal quality and processing speed?

What is the filter transition band provided 350 taps in standard tapped delay line LPF with sampling rate of 250 khz?

Suppose you have a digital audio signal sampled at a rate of 48 kHz, and you want to convert it to a lower sampling rate of 16 kHz. Design a decimation filter to perform the conversion and determine the decimation ...Read more

Why do we decimate signal in PRACH?

The PRACH signal in a 5G system has a bandwidth of 1.08 MHz. The receiver has a bandwidth of 200 kHz. What interpolation factor is required to upsample the PRACH signal to match the receiver’s bandwidth?

A discrete-time signal has a sampling rate of 1000 Hz and 200 samples. If you want to interpolate this signal by a factor of 2 using a zero-order hold interpolation method, how many samples will the interpolated signal have?

What is the filter transition band provided 290 taps in a standard delay line lpf provided the sampling rate of 500khz, k=2?

Why we use interpolation 1st, then apply decimation?
