To load a data set into the matlab workspace, type. The function then filters the result to upsample it by p and downsample it by q, resulting in a final sample rate of fs. The code rate is the ratio between the number of bits after crc coding and the number of bits after rate matching. Any effects of multipath fading, quantization, and amplifier nonlinearities must precede the effects of noise in the actual channel being modeled. I have posted quite a lot of projects on matlab but they are not well arranged thats why are not easily accessible. Automatically handle rate transition for data transfer. Your microphone will probably have a bigger sample rate set as default.

The problem here is the sampling rate seems to be varying. How to determine your audio cards, or usb mics, maximum sampling rate. This rate is directly linked to the baseband sample rate configured on the rf card and the valid data modeling within the user logic. Receiver interrupt the model runs at the rate at which frames of data arrive at the arm from the fpga.
