‫Now we come to the question that how do we set the parameters of people if he's Glock's and colonization
‫block?
‫But before that, it is important to tell you that basically there are two types of filters that are
‫used by this block.
‫The first type is the filter bank are a group of filters that is used for the recovery of the clock.
‫And the second filter is the root is cosine filter that is used for the removal of the inter symbol
‫interference.
‫So these are the two types of filters that are there in this block.
‫Now, how do we set the parameters of this block?
‫The first parameter is the simple spar symbol are it is the upsampling factor of the received signal.
‫For example, if the transmitter, the signal was up simply by a factor of four.
‫And when we receive that signal at the receiver as an input to this block, we set the value here is
‫for after that we have the loop bandwidth.
‫The loop bandwidth is basically the bandwidth of the filters that are used for the clock recovery.
‫And normally we set the value of this bandwidth as to by over a hundred.
‫And since BI has a value of three point one four.
‫So this value comes out to be zero point zero six school it.
‫So we normally set this value as zero point zero six squared.
‫Then we have the taps.
‫Now these are the types of the rubrics cosine filter that we are using and these types of rupiahs cosine
‫filter can be generated using the fear this library.
‫And within this library, we use the function of Rupak RES cosine, which as its import picks the gain
‫sampling factor, symbol, rate, access, bandwidth and number of apps as its import.
‫And as a result, it generates the coefficients.
‫Are the taps of the road race cosine filter?
‫And then you have the filter size, filter size basically indicates that how many filters are there
‫in the filter bank, which is used for the block recovery higher, the number of filters better is the
‫clock recovery, but also it increases the computational overhead.
‫For example, normally we said the value is thirty two.
‫But if we said this value, a 64 Gloc recovery would be better.
‫But on the other hand, computational complexity would be high.
‫And then we have the initial phase.
‫The initial phase is not very important.
‫You can set it as any value or example zero.
‫But here we have said its value as 16.
‫And then you have the maximum rate deviation, the maximum rate deviation is basically the deviation
‫in dissembles rate of the received symbols that are being input to this block.
‫And then you have these output samples per second.
‫And here we have set the value of one.
‫This means that at the input, if we have four samples per second, are the ups.
‫If you add the import, the upsampling factor is for the output.
‫It should be reduced to one.
‫So in this case, this block would decimate the input bu and upsampling factor of one.
