description Apparatus and method for compensating for transmitter errors in an optical communication system are provided. In certain configurations herein, a receiver is provided for processing an analog signal vector representing an optical signal received from a transmitter. The receiver includes an analog front-end that converts the analog signal vector into a digital signal vector including a digital representation of an I component and a Q component of the optical signal. The receiver further includes a digital signal processing circuit configured to process the digital signal vector to recover data, and the digital signal processing circuit includes a transmitter error compensation system that compensates the digital signal vector for at least one of a transmit skew error of the transmitter or a modulator biasing error of the transmitter.
