Summary form only given. The application of low-density parity-check (LDPC) codes to magnetic recording systems motivates the search for analytical ways to evaluate system performance over partial-response (PR) channels. In this paper a technique proposed by Duman and Kurtas (IEEE Trans. Inform. Theory, vol. 47, pp. 1203-1205, 2001) is extended to bound the frame error rate (FER) of high-rate LDPC codes. We circumvent the requirement that the weight distribution of the underlying code must be known by using estimates (A. Ashikhmin et al, ibid., vol. 47, pp. 1050-1061, 2001). This new bounding technique is used to compute the bounds for geometrically constructed LDPC codes over PR channels. Simulations are used to evaluate the computed bounds.
