There has been increasing interest for the coexistence of communication and radar systems which share the same wireless channel. This paper investigates the effect of non-cooperative additive radar interference for a communication channel where convolutional encoder is used. In order to include any given pair of convolutional encoder and M-ary constellation in the analysis, bit-error-rate (BER) bound expressions for low and high interference regions are derived based on product-state matrix technique. Thus, the any chosen constellation together with convolutional encoder does not need to satisfy the quasi-regularity (QR) property that includes geometrical uniformity and symmetry. Numerical results validate the derived performance bounds and using proper optimization techniques, the derived expressions can be utilized in search for good constellations for a given coding scheme suffering from radar interference without any restrictions on the constellation points and the choice of convolutional encoder.
