1. A method for configuring a quantizer to be used for quantizing a source for transmission over a noisy channel, the noisy channel having an average symbol error probability, the quantizer being configured to perform quantization using a respective quantization codeword for each region of a partitioned quantization space, the method comprising: calculating an updated set of the quantization codewords based on the partition of the quantization space and on the average symbol error probability; calculating an updated partition of the quantization space into regions using the updated set of quantization codewords; repeating the calculation of the updated set of the quantization codewords and the updated partition of the quantization space until a threshold is met; and configuring the quantizer to perform quantization, after the threshold is met, using the updated partition of the space and the updated set of quantization codewords.
