TABLE 1: A COMPARISON OF TURBO CONVOLUTIONAL CODES (TCCs) AND TURBO PRODUCT CODES (TPCs) FOR COMMUNICATIONS APPLICATIONS
Property	TCC	TPC	Comment
High QoS (BER < 10-6)		•	TCCs typically exhibit an error floor in the BER range of 10-5 to 10-9 (depending on code parameters).
			TPCs exhibit no such error floor.
High speed		•	TPCs have efficient decoding algorithms--fast ASICs are available today.
			TCC decoding algorithms are complex--no fast ASICs exist yet.
Low overhead (high code rate)		•	Code rate > 2/3.
			TCCs require puncturing to achieve high code rates, which is suboptimal.
Low QoS (BER > 10-6)	•		TCCs show slightly better performance at a high BER, particularly at lower code rates.
Low code rate	•		Code rate < 2/3.
			TCCs demonstrate slightly better performance with low code rates, particularly at high BERs, before the error floor limits performance.
Lower speed	•		TPC chips exist today that run in excess of 155 Mbits/s. Due to the complexity of TCCs, there aren't any practical ASICs yet.
Very high QoS (BER < 10-10)		•	TPCs exhibit a slight BER curve slope reduction at BERs in the range of 10-5 to 10-9 (depending on code parameters). Enhanced TPCs (currently available) eliminate this.
Intellectual property		•	TPCs are in the public domain. Fundamental TCC technology is patented.
