Abstract: A technique is disclosed for equalizing an incoming signal including quadrature-related carrier signals by forming the product of the incoming signal at at least one prescribed time and only one real-valued coefficient associated with each time. In one embodiment of the present invention, the equalized incoming signal is demodulated into a first pair of component signals. At least one of these component signals is then used to generate each coefficient. In another embodiment of the present invention, each coefficient is generated in response to at least one of the component signals in the first pair along with a second pair of component signals which are formed by demodulating the incoming signal. This technique can be advantageously adapted to incorporate a number of coefficient updating algorithms and is suitable for use in a number of modulation formats.

Abstract: Systems, methods and/or mobile devices are provided that enable a level of privacy/security in wireless communications to be increased responsive to a content of the wireless communications, biometric data and/or a position from which the wireless communications takes place. A plurality of communications modes is used by the system infrastructure and the plurality of mobile devices communicating therewith to increase privacy and undetectability of transmitted signals. The increased level of privacy and undetectability of signals is provided via pseudo-randomly generated signaling alphabets that are used by the mobile devices and by the system infrastructure to provide the communications. This represents a level of encryption/scrambling that is over and above the conventional encryption and/or scrambling at the bit level. Accordingly, systems, methods and/or devices providing a concatenated level of encryption/scrambling are provided.

Abstract: Numerous embodiments are provided that may be used to provide enhanced capacity and/or Quality-of-Service for OFDM-based systems such as LTE and/or WiMAX. Various service/device modes and/or applications are also provided. According to embodiments of the invention, a transformation may be performed on a data vector by a transmitter, prior to the transmitter transmitting the data vector, to distribute elements of the data vector over an available frequency space, thus providing robustness to channel anomalies such as fading and/or interference. The transformation may be based upon a Fourier transform or a truncated Butler matrix. At a receiver, an inverse of the transformation may be applied to recover data. The receiver and/or transmitter may be configured with an antenna array that may comprise a two-dimensional lattice of antenna elements, and may further be configured to estimate a number of resolvable signal paths and to form a spatial filter/rake that is matched to the number of resolvable signal paths. Embodiments relating to architectures, systems, methods, devices, software, firmware and/or computer program products are provided.

Abstract: Wireless communications are transmitted from at least two radioterminals to a base station co-channel over a return link using a return link alphabet. Wireless communications are also transmitted from the base station to the at least two radioterminals over a forward link using a forward link alphabet that has more symbols than the return link alphabet. The co-channel signals are deciphered at the receiver, while the radioterminals can use a smaller return link alphabet, which can reduce the power dissipation at the radioterminals.
