    Abstract: Some embodiments of the present application provide a forward-propagation-only (FP-only) method of training a DNN model. Such methods result in a trained DNN model whose performance comparable to a DNN model trained using bidirectional training methods. The FP-only method for training a DNN model may operate without employing the known chain rule. The chain rule is employed when computing gradients for a backward propagation in a bidirectional method. The FP-only method may allow for the computations and updates to the parameters for each layer of the DNN model to be performed in parallel. The FP-only methods for training a DNN model use stochastic gradient descent and the FP-only method for training a DNN model still involves computing gradients. However, the FP-only methods of training a DNN model allow for computing of gradients without the chain rule.

    Abstract: Aspects of this disclosure provide a technique for implementing polar encoding with incremental redundancy HARQ re-transmission. In particular, a transmitter encodes a message using different polar codes to obtain a first codeword and a second codeword that is twice the length of the first codeword, and transmit the first codeword as an original transmission, and the second half of the second codeword as a re-transmission without transmitting the first half of the second codeword. Information bits that are common to both the first codeword and the second half of the second codeword is mapped to more-reliable bit-locations in the second half of the second codeword. Decoded bit values for the common information in the original transmission and retransmission is compared by the receiver to perform a parity check.

    Abstract: An antenna system is described. A main antenna may be configured to receive a first signal, and a first auxiliary antenna may be configured to receive a second signal from a first expected interference direction. An adjustment unit receives the second signal and is configured to adjust the second signal. A combiner unit receives the first signal and the adjusted second signal and is configured to combine the adjusted second signal with the first signal to reduce any contribution of the second signal to the first signal.

    Abstract: This application discloses an information processing method and apparatus, a communications device, and a communications system. The method includes: encoding an input sequence by using a low density parity check LDPC matrix to obtain a bit sequence D, where a base matrix of the LDPC matrix is represented by a matrix of m rows and n columns, each column corresponds to a group of Z continuous bits in the bit sequence D, and both n and Z are integers greater than 0; and obtaining an output bit sequence based on a bit sequence V, where the bit sequence V is obtained by permuting groups of bits corresponding to at least two parity check columns in the bit sequence D.
