An entropy-constrained Trellis Coded Quantization (TCQ) scheme is presented for encoding memoryless sources. A simple 8-state trellis is used to encode the memoryless Gaussian source with mean-squared-error (MSE) performance within about 0.5 dB of the rate-distortion function. This performance is achieved at all non negative encoding rates.
