摘要： A vector slot processor that is capable of supporting multiple signal processing operations for multiple demodulation standards is provided. The vector slot processor includes a plurality of micro execution slot (MES) that performs the multiple signal processing operations on the high speed streaming inputs. Each of the MES includes one or more n-way signal registers that receive the high speed streaming inputs, one or more n-way coefficient registers that store filter coefficients for the multiple signal processing, and one or more n-way Multiply and Accumulate (MAC) units that receive the high speed streaming inputs from the one or more n-way signal registers and filter coefficients from one or more n-way coefficient registers. The one or more n-way MAC units perform a vertical MAC operation and a horizontal multiply and add operation on the high speed streaming inputs.

摘要： A wide band receiver to select and demodulate an input signal with single scan spectrum sensing by performing filtering on the input signal in digital domain to achieve improved selectivity and sensitivity is provided. The input signal includes one or more narrowband radio frequency (RF) signals. The wide band receiver includes a wide band tuner that down converts the one or more narrowband RF signals to one or more IF signals. An analog to digital converter (ADC) converts the one or more IF signals to one or more digital signals. A filter rejects out-of-band signals from the one or more digital signals to achieve the improved selectivity. A numeric controlled oscillator (NCO) selects at least one narrowband digital signal from the digital signals based on a phase value obtained from a spectrum selection control unit. A demodulator demodulates the narrowband digital signal to obtain a demodulated digital signal.
