What is equal gain combining?

Equal gain combining is a signal processing technique used in wireless communications to improve the reception of signals transmitted over multiple paths. It involves combining signals received from different antennas or paths, weighting each signal equally to maximize the overall signal strength and improve the signal-to-noise ratio. This method helps mitigate the effects of fading and interference, enhancing the reliability and quality of the received signal. Equal gain combining is particularly effective in environments with multipath propagation, where multiple copies of the same signal arrive at different times and amplitudes.
