Turbo codes with random interleavers are capable of achieving better error correcting performance than that obtained with structured interleavers at low SNR and the situation is in general the other way round at high SNR.To get better performance under the condition of various signal-to-noise ratios

this paper proposed a novel pseudo-random reverse block interleaver

which efficiently avoids the edge effect and combines the advantages of random interleavers and structured interleavers.Built in two proposed interleavers with different starting points

a novel Turbo encoder produced herein

capable of making Turbo codes obtains an increment in the minimum Hamming weight and consequently obtain a decrease at bit error rate.Simulation results show that the error-correcting performance of Turbo codes with it is superior to those obtained with other encoders on the whole when the short frame is transmitted.In particular

for clean channel

Turbo codes with the proposed encoder are capable of achieving much better error correcting performance than before.
