Webb11 sep. 2024 · Hello, To simulate an OFDM transmission I'm supposing that the delay spread is less than the cyclic prefix , so I define a signal matrix S where the columns represents the OFDM symbols and the rows represent the subcarriers (16 subcarriers) . so that the received signal in frequency domain will be Y=S.*H +N where H is the channel … The packet error ratio (PER) is the number of incorrectly received data packets divided by the total number of received packets. A packet is declared incorrect if at least one bit is erroneous. The expectation value of the PER is denoted packet error probability pp, which for a data packet length of N bits can be … Visa mer In digital transmission, the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization Visa mer As an example, assume this transmitted bit sequence: 1 1 0 0 0 1 0 1 1 and the following received bit sequence: 0 1 0 1 0 1 0 0 1, Visa mer The BER may be evaluated using stochastic (Monte Carlo) computer simulations.
