root raised cosine filter in cadence

hi i tried to understand the following parameters for root raised cosine filter in cadence but did not getting correct o/p.: alpha over_samples group_delay frame_time numChipsOut can any one guide how to set the parameters for 50Gb/s square wave for OOK modulation. Thanks

Need help with my Simulink QAM-OFDM Upsample to RF conversion

I have a simulink model (using Comm. Toolbox / DSP blocks) I have built that will do QAM modulation just fine with pulse-shaping (using root-raised cosine Filter). I'm trying to get a Baseband signal to RF for time-domain analysis for a RF PA. I need an LTE like signal with a high PAPR. So I am using an OFDM modulation on 16-QAM coding. (...)

difference in root cosine and root raised cosine in QPSK modulator?

hi there, i would like to know the difference between raised cosine and root raised cosine in qpsk modulator.thank you

where to put or place root raised cosine filter in QPSK modulator?

hi, i would like to know where to put the RRC at the modulator? whether before modulation process(Block diagram A) or after modulation process (Block diagram B)?is there going to be any difference between

About square root raised cosine filter design and pulse shaping

I have a set of symbol values to be modulated FM. Square root raised cosine filter is required for pulse shaping before FM modulation process. Roll off factor is given as 0.2. I wonder how transmitter pulse shaping filter order and its structure affects bit error rate after modulation and demodulation process?

Square root raised cosine filter with kaiser window

I want to know that square root raised cosine filter equation (following equation) can be used at both transmit and receive? h(n)= (4Rcos((1+R)2πnfc)+(sin⁡((1-R)2πnfc))/(8RkT_s fc))/(πF_s √(1/2fc)((8Rnfc)^2-1)) -∞

Function to get coefficients of root raised cosine pulse in Matlab

How could I do this function? = rootraisedcosine(P, B ,T) It has to generate a vector with 2P+1 coefficients of a root raised cosine filter with roll-off= B and period = T. stc so is an struct. I have read about rcosine, rcosflt and design.pulseshaping and don't (...)

square root raised cosine filter

hi all, m a b.tech student and doing a project on low power physical layer transceiver. but m stuck now in srrc filtering. i need to calculate the power taken by the square root raised cosine filter so that i can compensate by adding that much of power to the power amplifier. can anyone please suggest me how to calculate the power of a (...)

hi i need details regarding pulse shaping filter used in zigbee,plz help me

its urgent i need to submit,i did pulse shaping using rom but i need details regarding root raised cosine

Need a matlab code to design a root-raised cosine flieter

A doing my final year project which involves the design of a MIMO( multi-input Multi-output ) indoor wireless communication system where am required to use for transmit and four receive antennas, my problem is on how to design a pulse shaping filter( root-raised cosine filter) and interfacing the output of this filter(signal) to another PC (...)

problem coefficients of square root raised cosine filter

Hello I'm doing a square root raised cosine FIR filter, but with the formula that appears in the last page on this document I'm getting coefficients too high. There's a way to normalize those coefficients? Is right that formula for the square root raised cosine pulse shapin

QPSK/QAM symbol/phase sync, equalization etc.(simulink)

WCDMA Simulink error due to the Root Raised cosine filter

Hi! I am working on WCDMA simulation in Simulink. I have spreaded and scrambled the data as per the WCDMA standard and as per the standard i have to pass this complex data to root-raised cosine filter having roll off factor 0.22. I dont have idea how to adjust group delay parameter in it as i have not found or perhaps i dont know how (...)

Eye diagram for root raised cosine pulse

Impulse response of root-cosine filter is that it is zero at the positions of adjacent bits despite of that it "extends more" So Eye diagram is good

problem to calculate Eb/no with matlab

hi to all, I built a communication system with matlab using the QAM modulation method. I didn't use the Simulink?. allso I'm using the Square root raised cosine at the receiver and transmitter with rolloff 0.4 the system works fine but I have problem to measure the Eb/no. I can't use the AWGN function to add noise but only the (...)

Why we use raised root cosine or RRC filtering?

i have a question about why we use raised root cosine or RRC filtring, i am implementing BPSK, so if i have 1 i will send a cosine wave and if -1 i will send a 180 shifted cosine wave, RRC is done to make signal less vulnerable to inter symbol interference, but what i am sending on the channel is (...)
