摘要： The theme of our patent is an ultra low power components for Orthogonal Frequency Division Multiplexing (OFDM) based receiver. A new and innovationist OFDM receiver components ("our OFDM receiver components"), based on discrete time analog signal processing, are described in this patent application. OFDM receiver circuit is usually related to a communication field, where it is used to receive and decode a transmitted data. OFDM receiver circuit gets at its input OFDM modulated signals, and performs all necessary tasks, in order to decode the received data. OFDM signal comprised of multiple orthogonal carrier (103a- 105a), in which each one carries different data symbol. The summation of all carrier symbols comprises the data. To perform the receiving operation, an OFDM receiver must first perform detection, synchronization, parameter and channel estimation, then, a Fast Fourier Transform (FFT) is applied, and then, equalization is performed, and the last stage, is the de-interleaving and the error correction. All tasks above require complicated computational operations, such as additions, multiplications. Therefore, if implemented in a digital way, as it is with the current known technology, a significant high power is consumed by the receiver. Our OFDM receiver components are built and designed to work with discrete time analog signals, based on extremely low power additions, multiplications operations, and therefore achieves significant power reduction, compared to its digital counter implementation.

摘要： Channel estimation for high mobility OFDM channels is achieved by identifying a set of channel path delays from an OFDM symbol stream including carrier data, inter-channel interference noise and channel noise; determining the average channel impulse response for the identified set of channel path delays in each symbol; storing the average channel impulse responses for the identified channel path delays; generating a path delay curvature for each channel path delay in each symbol based on stored average channel impulse responses for the identified channel path delays; estimating the carrier data in the symbols in the OFDM symbol stream in the presence of inter-channel interference noise and channel noise from the OFDM symbol steam and the average impulse responses for the identified channel path delays; reconstructing the inter-channel interference noise in response to the path delay curvature, the identified set of channel path delays and estimated carrier data; and subtracting the reconstructed inter-channel interference noise from the OFDM symbol stream to produce a symbol stream of carrier data and channel noise with suppressed inter-channel interference noise.
