Performance of QPSK with Convolutional Code in Highly Reverberant Channel

摘要

In underwater acoustic (UWA) communication with high-speed, due to the initial situation of the channel, signal will inevitably be disturbed and error, adopt coding technique can improve the channel errors. Convolutional code as a Forward Error Correction (FEC), due to its excellent error correction performance is being widely used in the wireless digital communication system. In this paper, the performance of Quadrature Phase Shift Keying (QPSK) with convolutional code is analyzed in water tank considering Bit Error Rate (BER).
