An improved per-tone FEQ method with a noise reduction technique using periodic training pilot tones increases the throughput for long-reached modems. This method can reduce the noise effects in estimating FEQ equalizer coefficients. Each per-tone FEQ can be estimated by using the periodic training signals and an averaging technique to remove noise from each sub-channel (EQN. VI). After solving the system equations (EQN.

To demodulate a signal with the Toeplitz matrix, an inverse of every element in a row of the Toeplitz matrix is taken and multiplied by the sending signal which creates an N Log N matrix.

The present invention describes the system of centralized parking payment and monitoring, which uses geo-location enabled devices such as iPhone, android, RIM devices, mobile phones, pagers and wireless mobile computers.

Simultaneously, police or parking manager can also check the virtual parking receipt of the vehicle in the centralized parking system using Geo-location enable mobile device.

The big differences between this new solution is compared to existing solution are (1)

All the current solutions are identifying a particular parking spot instead of looking at holistic view of parking on a whole street or an unmanned parking area. Geo-location devices have 5-25 meters inaccuracy in identifying a position i.e. 1-5 parking spots inaccuracy. As a result, geo-location device cannot locate a particular parking spot. Thereby no public parking solution exists based on the geo-location based devices alone. In our solution, we re-engineered the business problem and instead of looking at a particular parking spot, the new process is dependent of parking of particular section of street or an unmanned parking lot—which we refer to ‘Parking Area’. The characteristic of Parking Area is that pricing and business apply to Parking Area as a whole unit. We are able to provide solution just based on geo-location based devices by combining concept of Parking Area with design of with parking application along with enforcement application. Parking Area will be divided in three level hierarchy Admin1, Admin2& Admin3. (2)

This solution does not need any new devices to be installed or parking spots to be marked and entered in the parking application. It uses geo-location enabled devices to identify the location of the parking place.
