Tuning VCP2 and TCP2 Bit Error Rate Performance
PDF, 293 Kb, Datei veröffentlicht: Feb 11, 2011
In most customer applications, a high level of decoding bit error rate (BER) performance is required. Since Convolutional codes and Turbo codes are widely used in wireless communication systems, TI DSPs integrate two high-performance embedded coprocessors (enhanced Viterbi decoder coprocessor and enhanced Turbo decoder coprocessor) that significantly speed up channel-decoding operations on-chip.
