20150230175 | MULTI-ACCESS COMMUNICATION SYSTEM - A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages. | 08-13-2015 |
20150188556 | System and Method for Analog to Digital Conversion - Parallel analog to digital converted (ADC) architectures that can be used to replace single path ADC architectures. The parallel ADC architecture can comprise N branches and one ADC per branch. These ADCs can be identical. However each branch can have a different path adjustments applied to the ADC. The path adjustments can be biases and/or gains and each ADC receives a different combination of biases and/or gain to generate multiple adjusted input signals. These are then combined to generate a quantised output signal. Using these parallel architectures a range of weighting and offset combining schemes can be employed to achieve improvements in signal to noise ratio and to reduce the impact of clipping as compared to a single path ADC architecture. | 07-02-2015 |
