This handbook provides the radio frequency (RF) analyst with the capability to calculate the effects of noise and interference on RF communications receivers. A receiver is modeled as a sequence of modules. Each module has a transfer function that relates the module outputs to the module inputs. By consecutively analyzing each module in the sequence, the analyst can then relate the receiver outputs (performance) to the receiver inputs (signal characteristics).

A wide variety of communications modulation and coding techniques are considered for this handbook including Quadrature Phase Shift Keying (QPSK), Gaussian Minimum Shift Keying (GMSK), Orthogonal Frequency Division Multiplexing (OFDM), Low Density Parity Check Coding (LDPCC) and Turbo Product Coding (TPC). Interferers considered include continuous and pulsed narrow and broadband interferers which are on-tune, off-tune and adjacent channel.

Pursuant to Section 6001(d)(4) of the American Recovery and Reinvestment Act of 2009 (ARRA or Recovery Act) (Public Law No. 111-5), the National Telecommunications and Information Administration (NTIA) provides this Quarterly Report on the status of the Broadband Technology Opportunities Program (BTOP). This Report focuses on the Program’s activities from July 1 to September 30, 2011, as well as overall accomplishments from Fiscal Year 2011.
