How to detect and estimate signals in noise?
Source Decod. Channel Chan. Encod. Chan. Decod. 1.1 Transmitter a) Information Source – analog signal: e.g. audio or video signal – digital signal: e.g. data, text b) Source Encoder Objective: Represent the source signal as efficiently as possible, i.e., with as few bits as possible ⇒ minimize the redundancy in the source encoder output bits
How to calculate the probability of a signal?
Schober: Signal Detection and Estimation 10 Intersection of two elements: E= A∩B Mutually exclusive events have as intersection the null element ◦/ e.g. A∩A¯ = ◦/. Associated with each event Ais its probability P(A) Axioms of Probability 1. P(S) = 1 (certain event) 2. 0 ≤ P(A) ≤ 1 3.
How is multi signal detection similar to digit recognition?
At the basic level, the multi-signal detection problem is similar to digit recognition. In fact, we will demonstrate that it is possible to train the published LaNet model to do multi-signal detection. We used the NVIDIA Digits application to train a LaNet model using a simulated dataset generated using Matlab code.

Which is the best method for channel estimation?
Channel Estimation is the process of finding correlation between the array of complex numbers on the left and the array of complex numbers on the right. The detailed method of the estimation can very depending on the implementation. The method that will be described here is based on the Open Source : srsLTE (Refer to [1])
How are signals detected in additive Gaussian noise?

How are complex numbers modified in channel estimation?
Each complex number (Reference Symbol) on the left (transmission side) is modified (distorted) to each corresponding symbols on the right (recieved symbol). Channel Estimation is the process of finding correlation between the array of complex numbers on the left and the array of complex numbers on the right.
