Re: [Discuss-gnuradio] A BERT Block with Offset Compensation

2014-10-16 Thread John Malsbury
Dan, The other thread on pulling data from vector_sinks and vector_probes has reminded me of a clever way to resolve this. 1) Write a simple function that accepts an array equal to your PN length, and determines alignment in the array. Maybe this function can take both the PN sequence, and a ve

Can you perform the alignment prior to the but comparison stage? This would simplify the comparison so that it can focus on BER alone and no alignment tasks. It would also address the following:Another issue that may arise if the bits streams are not aligned during comparison is that as you slide t

I am working on a GR block that will test two incoming bit streams (one a reference and one a received result) for equality and return the estimated BER. Blocks already exist that do this, but they assume the streams are aligned. My block will allow and correct for offsets in the bit streams. The
