Abstract
In this paper, an efficient anytime code derived from protograph-based low-density parity-check convolutional (P-LDPCC) code is proposed. Density evolution technique is applied to demonstrate the anytime properties of the P-LDPCC code over the binary erasure channel (BEC). Through simulation, the finite-length performance is evaluated and the effects of code design parameters are observed. The delay exponent is evaluated using the density evolution functions and simulations of finite-length codes. The simulation results show that P-LDPCC code outperforms existing LDPCC anytime codes.
